Attention
The antenna(s) used for this transmitter must be fixed-mounted on outdoor
permanent structures with a separation distance of at least 6 meters from all
persons during normal operation. The peak conducted output power at each
antenna terminal must not exceed 60 Watts and the peak radiated output power
must not exceed 250 Watts EIRP. Users and installers must ensure that FCC
requirements for satisfying RF exposure compliance are met. (See FCC Rules Part
1, Sections 1307 and 1310)

4) Programming
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 (time
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. Keep the EXT/CH at low level, then switch ON, radio
works as remote mode. If you switch ON first, prior to the LOW level, no remote mode is activated.
To recover normal mode, EXT/CH set at HI. Please note the maximum channels through remote
control is up to 256 channels.
