CARE OF OPTIONAL RECHARGEABLE Ni-Cd BATTERIES
e 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.
•
•
•
e 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. e volume level and squelch control setting;
C. e channel selector for an active channel;
D. e 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). e display turns off when the squelch is operative.
5. “BATT. LOW” LED: is indicator lights when the batteries are low. Replace the alkaline or recharge the AA
Ni-Cd batteries.
6. “TX” LED: e 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).

HOW TO OPERATE WITH YOUR TRANSCEIVER
1. Insert the antenna into the antenna connector.
2. Insert 9 AA alkaline or Ni-Cd batteries into the battery compartment (pay attention to the polarity). When
using Ni-Cd batteries, switch the interrupter inside this compartment to “Ni” position: in this way, the Ni-Cd
batteries can be charged by an optional charger. Select the “AL” position when using the alkaline batteries.
3. Rotate the ON/OFF volume control clockwise to turn the unit on. Adjust the volume to the desired listening
level.
4. Adjust the SQUELCH control.
5. Select the desired channel using the “UP/DOWN” buttons.
To transmit: Press and hold the PTT button, then talk to the microphone.
To receive: Simply release the PTT button.
ANTENNA
e 75-785 antenna connector permits the use of any kind of 50 Ω/ 27 MHz band antennas.
Better results both in RX and TX can be obtained by using a telescopic antenna. e supplied rubber antenna,
however, is more compact and practical to use. It is suitable for communications where maximum range is not
necessary.
POWER JACK/RECHARGE
is jack enables you to power the unit using an external power source or directly with the battery of your
vehicle using the supplied power cord (the plug must be connected to the power source).
e jack, also, permits the recharge of Ni-Cd batteries through an optional charger. (Attention: To recharge these
batteries, switch the interrupter inside the battery compartment onto the “Ni” position.)
CB COMMUNICATIONS CODES
Radios operators have universally adapted the “10” code for standard communications. It enables them to
communicate more easily in noisy surroundings.
Here below you will find some of the most common codes and their meaning:
