(3) Public Announcement (PA) Mode
1.
When the PA switch is turned on, the LC7185 stores the value of the previous channel and enters the PA mode.
2.
While the PA switch is turned on, the LC7185 disables all keys (TX, CH9/CH19, UP/DN, ME, M1 to M5)
3.
‘‘PA’’ is displayed on the channel display.
4.
When the PA switch is turned back off, the LC7185 enters the CB mode and reopens the previous channel.
5.
The UL line is asserted while the PA switch is turned on.
(4) Transmit/Receive Selection
1.
When the TX line is asserted, the LC7185 enters TX mode.
2.
If the PA switch is turned on while the LC7185 is in TX mode, the device enters PA mode. However, if any other
switch (other than the PA switch) or key (UP/DN, ME, M1 through M5, CH9, CH19) is pressed while the LC7185 is in
TX mode, that switch or key has no effect.
3.
The unlock detected signal is output each time the device switches between transmitting and receiving.
(5) Channel Preset/Recall Facility
1.
The LC7185 allows up to 5 channels to be preset (assigned to M1 to M5).
.
After a reset (when the power is turned on, etc.), M1 to M5 are assigned to CH33.
2.
Recalling preset channels
.
A preset channel is recalled by pressing one of the preset memory keys (M1 to M5) to which the channel was
previously assigned.
.
There are two different display modes as shown below.
Mode 1 (without diode)
Each time a key is pressed (M1 to M5), the new channel is displayed.
Example: Display 21
→ 15
key
M1
Mode 2 (with diode)
Each time a key is pressed (M1 to M5), a key mnemonic (‘‘P1’’ to ‘‘P5’’) is displayed for 400 ms, then the new
channel is displayed.
Example: Display 21
→ P1 → 15
400 ms
Key
