this key recalls channel 9. Pressing the [16/9] key again reverts to the
previous selected working channel.

[WX] Key
Immediately recalls the previously selected NOAA weather channel from
any channel.
Secondary use

the mode from USA to International or Canadian.
2. Holding down the [WX] and [SCAN] key while turning the power on
resets the microprocessor and erases scan channels from memory.
This clears the memory and establishes the factory-set defaults. For
a list of these defaults, see the section on 6.19 Resetting the
Transceiver’s Microprocessor.
[SCAN] / [MEM]Key

2. If held while the [UP()] or [DOWN()] key on the microphone are
pressed or CHANNEL selector knob on radio is turned, the radio will
show the channels programmed in scan memory. This function will
not work if the unit is scanning.
NOTE: The priority channel is channel 16 only.
3. Pressing and holding again will delete the channel from scan memory.

pressed while the transceiver is on channel 13 or 67, the power will tempo-
rarily switch from LO to HI power until the PTT is released. The [H/L] key
does not function on transmit inhibited and low power only channels.
Secondary use
Press and hold [H/L] key, the LCD displays NAV GPS Data, Time, SOG
(Speed Over Ground), and COG (Course Over Ground) when a GPS is
