SECTION 2 – OPERATING
INSTRUCTIONS
2.1 FEATURES
The equipment has several important operating features which provide maximum flexibility,
performance and versatility. These features include:
1. The UHF band can be configured to be operated independently of the VHF High and VHF
Low bands or all three bands can operate as a single unit.
2. The unit can be set up as a cross band repeater, linking a VHF High and UHF frequency
in both directions. The VHF Low band will not cross band repeat.
3. 200 memory positions per band which can each be programmed with a transmit and
receive frequency with 25 or 12.5 kHz channel spacing, Tx/Rx CTCSS tones or DPL
codes and a 9-character alphanumeric title.
4. Scanning of preprogrammed memories with selective memory scanning, in up to 5 scan
lists, for the VHF High or UHF band. The VHF Low band does not scan.
5. Priority scan of memory channel 1 in VHF high or UHF band. The Scan function can only
be used for one of these bands at a time. Simultaneous scanning on both bands is not
possible.
6. Direct frequency entry mode.
7. Receive frequency simplex function. (Repeater talk around)
8. Switchable RF output power between 1 watt and 8-10 watts.
9. Lockout of keyboard to prevent inadvertent entries.
10. Variable frequency mode to manually scan up and down in 1 MHz, 100 kHz or 2.5 kHz
steps.
11. LED display variable dimming mode.
12. Selectable 90 second Tx time out feature.
13. PC Memory Upload or Download capability.
14. Configuration Menu: Pressing ENTER, RCL and FUNC together, while turning the radio
on, will put it into configuration mode. The programming features affected are:
a) DPL - Can be turned on or off with the MUP and MDN (4 and 7) keys.
This only removes the DPL entry step from the programming
sequence and does not stop memories that already have DPL
codes from working. This also applies to the rest of the on/off
configurable items.
b) Scan - Can be disabled. Selecting FUNC and SCAN will do nothing if
Scan is off. The scan list indicator (+) will still display if was
previously programmed.
c) Rx CTCSS - Can be turned on or off from the programming sequence. This
affects only the CTCSS tones for receive.
d) LAST MEM - If set to on, the last memory channel on the display will be what
comes up when the radio is turned on. If set to off, the last
memory that changes were made to will be what comes up
when the unit is switched on.
e) DUALMODE - If set to ON, the UHF band is operated independently from the 2
VHF bands. (Example: UHF audio separately available on 9 pin
connector). The radio is shipped with this feature OFF.
