The Dual Watch feature allows the user or dispatcher to
operate on one channel while periodically making a brief
check of Memory Channel “1-001” (Memory Bank #1,
Channel #1). The Dual Watch feature can be engaged so
long as there is frequency and mode data written into
memory channel “1-001.”
Every four seconds, the transceiver will automatically
switch over to memory channel “1-001.” If a station is
transmitting on memory channel “1-001,” one of two
things will happen:
If the
VX-1700
is in the “Carrier Drop” mode, the
transceiver will hold on memory channel “1-001” un-
til the transmission ceases. The transceiver will con-
tinue to hold for ten seconds after the transmission
ends, in case the other station decides to resume trans-
mitting. After the three second delay, Dual Watch will
resume, with your original operating channel (not
memory channel “1-001”) being restored to the Main
Display.
If the
VX-1700
is set to the “Time Delay” mode, the
transceiver will hold on memory channel “1-001” for
five seconds, then Dual watch operation will resume
(irrespective of the transmit/receive status of any sta-
tions on memory channel “1-001”).
Dual Watch operation is simple to use. Follow these steps:
First, set the desired “Resume” mode for Dual Watch.
Usually, this will be “Carrier Drop,” which will not
allow the transceiver to move off memory channel 1-
01 if someone is still transmitting. To do this, press
the [
F
] key followed by the [
8
(
DW
)] key, then rotate
the
CH
Selector knob until “
CARR
” is shown in the
LCD display. If you prefer the “Time Delay” mode,
rotate the
CH Selector knob until “ TIME ” is displayed.
Now press the [
8
(
DW
)] key again to return to the nor-
mal display.
Adjust the SQL control so that the “ ” icon dis-
appears and the receiver is silenced.
Press the [
8 ( DW )] key to activate Dual Watch. After
four seconds, the transceiver will switch over to
memory channel “1-001,” and will stay there for 1/2
second, thereafter returning to your original channel.
If a call is received on memory channel “1-001” dur-
ing Dual Watch operation, the transceiver will lock
onto that channel, then resume in accordance with the
“Resume” mode selected previously.
Press the [
8 ( DW )] key again to disable the Dual Watch
feature. Operation will revert to your original operat-
ing frequency.
Note that your main operating channel can be changed
during Dual Watch operation, but you cannot change
channels while memory channel “1-001” is being
checked for activity.
