CARE OF OPTIONAL RECHARGEABLE Ni-Cd BATTERIES
The following is meant as general information regarding Ni-Cd batteries.
• Always allow the battery to fully charge before using.
• Allow the batteries to fully discharge before recharging. Full discharge will be indicated by the
“BATT. LOW” indicator.
• The above will prevent the batteries from developing “memory” which effectively reduces their capacity.
• It is better to store Ni-Cd batteries that are discharged rather than charged.
• Never use batteries which differ from the ones recommended. Do not mix old and new batteries or batteries
of different capacities.
• If you experience problems when using the transceiver, check the following:
A. Batteries must be in good condition;
B. The volume level and squelch control setting;
C. The channel selector for an active channel;
D. The antenna must be properly inserted.
CONTROLS AND INDICATORS
1. Antenna connector with BNC connector: To obtain better results, use either a telescopic or an external
antenna.
2. Squelch Knob: for the maximum receiver sensitivity, the control must be regulated exactly where the receiver
background noise disappears.
3. On/Off Volume Control: In “OFF” position your transceiver is off. Turn this control clockwise to switch on
the unit. Continue turning the knob clockwise to set the audio level, until you get a comfortable reception.
4. Display: Indicates the selected channel (from 1 to 40). The display turns off when the squelch is operative.
5. “BATT. LOW” LED: This indicator lights when the batteries are low. Replace the alkaline or recharge the AA
Ni-Cd batteries.
6. “TX” LED: The indicator lights when the unit is transmitting
7. Speaker
8. Microphone: during transmission, hold the microphone two inches from your mouth, speaking in a clear,
normal voice.
9. Push to Talk Button (“PTT”): By pressing it, the transmitter is activated. When released, you activate the
receiver.
10. “Channel UP” button: Tunes to the next channel. Autorepeat is activated by holding this button.
11. “Channel DOWN” button: Tunes to the previous channel. Autorepeat is activated by holding this button.
12. “SPK” jack: external loudspeaker jack (the internal loudspeaker will be disabled).
13. “PTT/MIC” jack: PTT jack / external microphone.
14. 13.8 VDC Charge: Power supply/charge jack. You can power the unit from external sources (car battery, etc.)
and to recharge the Ni-Cd batteries.
15. “HI/LOW” Switch: Selects the output power level during transmission.
16. Battery Compartment: Insert 9 AA alkaline or Ni-Cd batteries. (Note: alkaline batteries are not
rechargeable).
17. Belt Clip
18. Hole for wrist strap
