Technical Characteristics; Trouble Shooting; How To Transmit Or Receive A Message - PRESIDENT WALKER Classic Manual Del Usuario

The scanning automatically starts 3 seconds after the end of the transmission
if no key is activated. The scanning starts again in an increasing way by using
the "UP" (5) key of the microphone or in a decreasing way with the "DN" (5)
key of the mike.
TOT (Time Out Timer)
If the PTT key (16) is pressed for more than 5 minutes, the transmission ends,
RX/TX Led and Channel blink. Released the PTT key (16) and press it again to
continue.

D) TROUBLE SHOOTING
1) YOUR CB RADIO WILL NOT TRANSMIT OR YOUR TRANSMISSION
IS OF POOR QUALITY
- Check that the PA function is not activated
- Check that the antenna is correctly connected and that the SWR is properly
adjusted.
- Check that the microphone is properly plugged in.
- Check that the configuration is the correct one (see table page 45).
2) YOUR CB RADIO WILL NOT RECEIVE OR RECEPTION IS POOR
- Check that the PA function is not activated
- Check that the squelch level is properly adjusted.
- Check that the configuration is the correct one (see table page 45).
- Check that the volume is set to a comfortable listening level.
- Check that the microphone is properly plugged in.
- Check that the antenna is correctly connected and that the SWR is properly
adjusted.
- Check that you are using the same modulation mode as your correspondent.
3) YOUR CB WILL NOT LIGHT UP
- Check the power supply.
- Check the connection wiring.
- Check the fuse.
E) HOW TO TRANSMIT OR RECEIVE A MESSAGE?
Now that you have read the manual, make sure that your CB Radio is ready
for use (i.e. check that your antenna is connected).
Choose your channel (19, 27).
Choose your mode (AM/FM) which must be the same as that of your corre-
spondent.
