Base Tech III can be programmed through PC at anytime when RX mode. Programming is not
possible while Base Tech III in key entry.
When programming is started, the LCD indicates as shown.
Figure-1 shows Data from radio to PC,
Figure-2 shows Data from PC to radio.
If the program software is not communicating properly, the radio will re-write again and again
(endless). When this happens, keep depressing SHIFT and switch on the radio. Then the radio will
recover.

22) Repeater mode
BASE TECH III repeats automatically when programmed as a repeater.
a) Rx mode = digital
Repeats only the same NAC code. If the NAC is $F7F, all incoming signals are repeated. .
Repeating shuts automatically after 0.0-9.9 seconds if no incoming signal is detected (Hang Timer
-programmable).
b) Rx mode = Mix
In addition with above conditions, radio repeats the correct CTCSS,
DCS are detected, or only the carrier as well.
Radio can not repeat analog and digital at the same time.
23) Remote control
BASE TECH III can be controlled by remotely. Pull the EXT/CH at low level, radio works as remote
mode.
To recover normal mode, EXT/CH set at HI. Please note the maximum channels through remote
control is up to 16 channels.
