These combinations of buttons can be programmed for None, Scan, Dual Watch, VOX or Whisper. Function Description None When the button assigned to None is pressed, there is no action. Scan When the button assigned to Scan is pressed, the radio proceeds to scan the memory list.
2: Radio Basics Scroll Buttons Scroll ▼ • To scroll down programmed channels when the channel knob is in the F position. • To scroll down through the squelch levels. • To access the programming mode when MONITOR is also pressed. Scroll ▲ • To scroll up programmed channels when the channel knob is in the F position. • To scroll up through the squelch levels. • To access the cloning mode when MONITOR is also pressed.
2: Radio Basics LCD Display and Icons Icon Description Monitor indicator. If displayed, monitoring is activated. Its activation disables audio mute. If displayed, the key lock is activated. Its activation prevents the buttons from functioning (with the exception of PTT and MONITOR). Unlock by pressing MONITOR at least 2 seconds. Unused at this writing. If displayed, the 150 Hz tone has been programmed into the radio for the displayed channel.
2: Radio Basics Audio Signal Tones Refer to this table to ascertain the high or low pitched (tone) frequency beeps. Knowledge of these tones allows monitoring of the radio without looking at the display. Reason for Beep Output (1 cycle) Remark Power on Enable/disable using Programmer SHIFT or MONITOR button enabled or channel knob turned Enable/disable using Programmer SHIFT or MONITOR button released Enable/disable using Programmer. Two beeps.
2: Radio Basics Battery Information If the battery is new (it is shipped empty) or its charge level is low, it needs to be charged before use. The radio beeps if the voltage goes below 6.5V. Detection and beep is only indicated once. To charge the battery: 1. Turn the radio off and plug the charger into the power source. 2. Place the battery (with or without the radio attached) into the charging pocket. 3. Remove the battery when the indicator is a steady green.
2: Radio Basics To remove the battery: 1. Turn off the radio. 2. Slide the battery latch toward the front of the radio into the unlock position. 3. With the battery latch engaged, slide the battery away from the top of the radio.
2: Radio Basics Attaching the Belt Clip 1. Using your thumb, press the clip’s spring latch towards the top of the clip. Slide the latch down into the groves of the radio and release your thumb. 2. Place the screw on top of the phillips screwdriver and keep it in place while passing the screwdriver through the opening of the clip. 3. Tighten the screw to the battery. Removing the Belt Clip 2-8 1.
3: RADIO OPERATION The HH7700 operates with most of its features already programmed into the radio. Request a list of the functions that are assigned to the buttons and switches on your radio. Quick Start Before proceeding, the radio must be set up using the HH7700 software Programmer. 1. Battery Install a charged battery. 2. Antenna Install the antenna. Do not operate the radio without an antenna. 3. Power-up Turn the power/volume knob clockwise about halfway around.
3: Radio Operation If a channel has not been assigned to a position, NO-CH is displayed. To access the channels that are not preset: 1. Turn the channel knob to F. 2. Press ▲ or ▼ to scroll through the channels. 3. Press SHIFT to display the channel’s frequency. Note: The radio is programmed to display either channel numbers or channel frequencies. It is not possible to display both. Setting Output Power The power level can be set for each channel (high, medium or low). To set the power level: 1.
3: Radio Operation Receiving a Call 1. Turn the radio on. 2. Adjust the volume. 3. Select the desired channel. 4. Listen for voice activity. The LED indicator flashes green while the radio is receiving. 5. To respond, hold the radio 1 to 2 inches from your mouth. Press PTT to talk. The LED turns red. Note: The radio can be programmed to enable a timeout from 0.5 seconds to 4 minutes. The call may terminate if the call time is exceeded. Sending a Call 1. Turn on the radio. 2. Select the desired channel.
3: Radio Operation Setting Squelch Level To set the squelch level: 1. Navigate to the channel to set. 2. Press SHIFT and MONITOR. 3. Press ▲ to scroll up through the 16 squelch levels and press ▼ to scroll down through the 16 squelch levels. 4. Press SHIFT to release the squelch level function. Note: If a button is not pressed during squelch level changes, this mode terminates automatically after 5 seconds. Scanning There are two types of scanning: Memory and Dual Watch.
3: Radio Operation Memory Scan More than 1 channel must be assigned to the memory scan list for scanning to take place. Scanning can be viewed in channel mode or frequency mode. 1. Turn the Channel knob to the F position. 2. Press SCAN. The radio scans the memory list in a continuous loop at a speed set in the Programmer (from 50 ms to 120 ms). The example below shows an uninterrupted Memory scan (no activity detected).
3: Radio Operation When a signal is detected on a channel, the monitor icon is displayed, the channel or frequency flashes and activity on the channel is heard. Scanning pauses for 5 seconds unless tone decoding is enabled on some or all channels causing the scan rate to slow down as the radio decides whether or not there is something worth listening to. When the signal ends or 5.0 seconds is up, scanning resumes. 3. Press SCAN again to stop scanning.
3: Radio Operation programmed frequencies and channel 12 is the priority channel. After scanning the priority channel, the scan cycle continues with channel 1. When a signal is detected on a channel, the monitor icon is displayed, the channel or frequency flashes and activity on the channel is heard. Scanning pauses for 5 seconds unless tone decoding is enabled on some or all channels in which case the scan rate slows down as the radio decides whether or not there is something worth listening to.
3: Radio Operation To scan a Preset channel with a Priority channel: 1. Turn the channel knob to one of the Preset channels (1 to 15). 2. Press DUAL WATCH. The radio begins to scan the radio looking for the Preset channel and the Priority channel (setup using the Programmer) to monitor. In the example below, the Preset channel is 5 and the priority channel is 1. When a signal is detected on a channel, the monitor icon is displayed, the channel or frequency flashes and activity on the channel is heard.
3: Radio Operation Key Lock Feature The key lock feature prevents the accidental pressing of radio buttons with the exception of PTT and MONITOR. To activate this feature: 1. Press MONITOR for more than 2 seconds. Doing so displays the key icon . The key lock status is retained when the radio is turned off. 2. Release the key lock by pressing MONITOR again for more than 2 seconds. The key icon is no longer displayed.
3: Radio Operation Back Light Feature The back light is enabled using the Programmer and can affect the display area and buttons on the radio in various ways: • On After Key. The light goes on after any key is pressed (default). It lights up for 1 second when the radio is turned on and for 5 seconds when the channel knob is turned or any other button is pressed (pressing any key within this 5 seconds extends the light 5 seconds longer). • Always on. The light is always on. • Disable.
3: Radio Operation Whisper Feature Whisper increases the sensitivity of voice transmission. The validity of its use must be taken into consideration before being programmed into the radio. A WHISPER button must be assigned by the Programmer for this feature to work. When Whisper is enabled, W is displayed. When scan is activated, Whisper is overridden. The Whisper status is retained when the radio is turned off. CAUTION: Not to be used with the VOX feature.
3: Radio Operation Programmed Settings The following settings are programmed using the Programmer. For details, refer to the HH7700-PROG-MSOP Programmer guide.
