Using the Transceiver as a Megaphone (Public Address)
Public Address (PA) enables the transceiver to be used in place of a megaphone. This function is used for a bus
announcement, etc.
This section describes behaviors unique to a Multi RF Deck/ Multi Control Head structure.
Public Address can be toggled between enabled and disabled by any of the following key operations:
1.
Pressing the Public Address key toggles Public Address between enabled and disabled.
2. Entering Menu Mode by pressing the Menu key, and then executing “Public Address” can toggle Public Address
between enabled and disabled.
Public Address functions by using the external speaker (KES-3 or KES-5) connected to RF Deck 1. Therefore, the behavior
of RF Deck 1 is restricted as follows:
0
While Public Address is enabled and the PTT switch is pressed, RF Deck 1 does not perform the reception behavior.
The other RF Decks perform the reception behavior regardless of the status of the PTT switch.
0
The operation to toggle Public Address between enabled and disabled is available only if the Selected RF Deck is RF
Deck 1. When the Selected RF Deck is RF Deck 2 or RF Deck 3, the operation to toggle Public Address between enabled
and disabled is unavailable.
If the External PTT (PA) is entered from the AUX Input port of RF Deck 2 or RF Deck 3, the audio is emitted from the external
speaker of the RF Deck from which the External PTT (PA) is entered.
