INTRODUCTION This section contains DEFINITIONS AND ACRONYMS information concerning the operational ANI Automatic Numeric Identification CG Channel Guard CLR Clear Channel Guard A subaudible tone, a code (analog) or a Network Access Code (digital) for selective calling and receiving. DTMF Dual Tone Multiple Frequency interoperate with narrow or wide band analog channels as well as DTMF Tones Tones that sound like those used by a standard push-button telephone. digital systems.
CHANNEL LABELS You can program the radio with a label for each of the 25 channel groups and a label for each of the 16 channels within each group. To display the channel number associated with a channel label: 1. Press the microphone’s [#] key to display the group number. 2. Press the [#] key again to display the channel number. 3. Press and hold the [#] key to display the channel label. 4. Press the [ENT] key or wait for about 5 seconds to revert to normal radio operation.
FEDERAL COMMUNICATIONS COMMISSION REGULATIONS BUSY CHANNEL LOCKOUT WITH OVERRIDE The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for mobile 2-way radios before they can be marketed in the U.S. When 2-way radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to control their exposure to meet occupational requirements.
RF EXPOSURE COMPLIANCE AND CONTROL GUIDELINES AND OPERATING INSTRUCTIONS BUSY CHANNEL INDICATION The yellow Busy Channel Indicator glows if there is carrier activity on the selected channel. If the selected channel is a Channel Guard channel and the proper Channel Guard value is not detected, the Busy Channel Indicator remains on for the duration of the carrier activity and no message is heard.
DTMF ENCODING (Analog Mode Only) RADIO CONTROLS Transmit Indicator Radios with keypad-equipped microphones can be programmed to enable DTMF (Dual Tone Multiple Frequency) encoding. To send DTMF tones (similar to the tones used by a standard push-button telephone): Display Dimming Sensor Priority Indicator Busy Channel Light Function Button On/Off Indicators 1. Press and hold the PTT switch. 2. Press any of the keys on the microphone’s keypad.
4. Press the microphone’s [#] key to display the Channel Guard channel briefly. The display shows the group number, followed by the Channel Guard channel, and then the selected channel. 5. Press the [0] key to reset all values to the original programming, or press different number keys (116) to select a different set of Channel Guard Values. NOTE: During Scan or Priority Scan, the receiver does not use the user-selected Channel Guard values.
APCO PROJECT 25 SQUELCH CONTROL Network Access Codes (NACs) provide the digital equivalent of analog sub-audible signaling (CTCSS/CDCSS) allowing a group of radios to be selectively called within a system. Users in the same area (using the same NAC) can be further divided into Talk Groups, with each group having its own Talk Group ID (TGID). Group Calls are made by designating both the users’ NAC and TGID. Each radio also has an individual P25 unit ID.
1. Press the [#] key to toggle a decimal on or off to the right of the character in position 7. The decimal moves left with the number in position 7 as new numbers are entered. 2. Use the following steps to enter a number in position 8 or characters in positions 1-8: a. Press the [PRI] key repeatedly to cycle through characters 0-9, A-Z, -, *, $, /, +, %, \, |, _, <, >, h, blank, then back to the start again.
CHANNEL GUARD TRANSMIT 1. Monitor the channel, before transmitting on Channel Guard channels, by lifting the microphone off hook or pressing the [MON] button. Listen to the channel for a few seconds to ensure that no communications are occurring on the channel. 2. Press the PTT (Push-To-Talk) switch on the microphone. The TX annunciator appears on the display and the red Transmit indicator illuminates while the PTT is pressed.
If Unit-To-Unit Mode is entered when the RTX channel is programmed for analog-only transmissions, pressing PTT will cause the radio to beep until PTT is released. The user must select a channel capable of digital transmissions before placing a Unit-ToUnit call. If the RTX channel is programmed for Mixed Mode transmit, transmissions will be made as digital Unit-To-Unit calls while the radio is in Unit-ToUnit Mode, regardless of the position of the ‘TX Digital’ switch.
The display indicates Secure Operation as follows: 1. In Standby Mode, if the radio will transmit in Secure Mode when PTT is pressed, the encrypt icon flashes in the display. 2. When receiving or transmitting an encrypted signal, the encrypt icon flashes in the display. TRANSMIT KEY SELECTION The radio can hold up to 32 DES or AES encryption keys. Each channel is assigned a default key for transmit.
To reply to a message heard on the priority channel, press the PTT switch. The radio transmits only on the priority channel when Priority Scan is on. Once activity has ceased on the priority channel, the radio returns to scan operation. CHANGE THE PRIORITY 1 CHANNEL The fixed Priority 1 channel can be permanently set or can be changeable. If the radio has a changeable priority channel, use the following steps to make this change. 1. Turn Scan and Priority Scan off. 2.

The table below shows how the priority channels and the transmit channels are selected in each mode. Mode A Mode B Mode C Priority Channel Channel Knob Preset Preset Transmit Channel Channel Knob Channel Knob Priority Channel Press the [MON] button to start or stop monitoring squelch noise.
Press the [SQL] button for Squelch Adjust Mode. Turn the Volume knob to adjust the squelch setting. Turning the knob counterclockwise tightens the squelch setting, allowing only stronger signals to open the squelch and be heard. In the absence of a held channel, the receiver will be tuned to the main channel. Guard qualification will be disabled during squelch adjustment. Return to Volume Adjust Mode by waiting 5 seconds, or by pressing the [SQL] button again.
HOM CHANGE THE SCAN LIST Press the [HOM] button to go to the preprogrammed Home Channel. The radio can be programmed to enable the user to add or remove channels from the scan list. If user changes are enabled, follow these steps to change the scan list: To set a different Home Channel, select the desired channel using the Channel Selector knob, press the [HOM] button, and hold it for more than 1 second until the arrow above the HOM button appears on the display.
PA Public Address Press the [PA] button to turn the Public Address system on or off. When PA is on, pressing the microphone PTT switch causes audio to be routed to the audio amplifier without enabling the transmitter. ACC Accessory Press the [ACC] button to turn the installed accessory on or off. Up to three ACC buttons may be installed for different accessories. SCAN OPERATION RECEIVE Scan operates only while the radio is not transmitting.
