Fig. 4 Feature Column Double-click on the any window inside red-rectangle area to set Rx,Tx frequency, Rx, Tx option for each channel. 4.2.2.1 Power 150. 150. 150. 150.
Shenzhen Friendcom Technology Development Co., Ltd. User can decide the channel spacing in this feature with optional 6.25KHz (Narrow) or 12.5KHz (Wide) channel spacing. 4.2.2.3 SQ level Five SQ levels can be select in our radio. Level 0 is for fully open mute. The audio signal will continuously transmit. Other levels with corresponding strength are shown as below: L1: 0.15uV L2: 0.25uV L3: 0.35uV L4: 0.45uV L5: 0.55uV 4.2.2.
Shenzhen Friendcom Technology Development Co., Ltd. CTCSS/DCS User can encode tones with CTCSS/DCS according to options shown in the picture. The feature is not available for high speed data transmission. Switch When we use radio remote: the Switch function can be use to change a logic from +5V to 0V minimum. The judging condition is long period of 260Hz, sine wave 300 Ms. 4.2.2.5 Scan This feature allow user to decide scan mode and establish channel scan list.
Shenzhen Friendcom Technology Development Co., Ltd. 4.2.3.3 Second Column Features 4.2.3.3.1 LED Status Indicator The LED indicator gives realtime status of the radio's operation. Red for TX, and green for RX. 4.2.3.3.2 TX Protection This feature, when enabled, limit the amount of time that user can continuously transmit. The time can be set from 1 second to 60 seconds. When timeout, radio will release PTT pinout.
Shenzhen Friendcom Technology Development Co., Ltd. Power Save Time When Power save is enable, sleep time can be programmed from 20 to 500 ms in 20ms increment with 1~25 optional values. That means 1 equals to 20 ms, 2 equals to 40ms ....... 25 equal to 500ms Standby time can also be programmed from 40 to 600 ms in 40ms increment with 1~15 optional values. That means 1 equals to 40ms, 2 equals to 80, ..... 15 equals to 600ms. 4.2.3.3.
Shenzhen Friendcom Technology Development Co., Ltd. Scan modes are set up in “Option” and shown as below 0 ---------normal scan with carry only 1 ---------normal scan, carry with tone 2 ---------priority scan, carry only 3 ---------priority scan, carry with tone If normal scan is enabled, radio will scan from initial channel to channel 16 sequentially. If priority scan is enabled, radio will scan the prioritized channel with more times. Prioritized channel is the working channel before the scan.
