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.
