Communicating Directly Between Control Heads (Intercom)

Intercom is the function to directly communicate (simplex communication) between Control Head 1 and Control Head 2
with a wired connection. The function is for Dual Control Head. This function is used as means of contact between 2 Control
Heads when the Control Heads are at remote locations.
Pressing the PTT switch of a Control Head when Intercom is on emits the audio from the speaker of the other Control Head.
Intercom can be toggled between on and off by any of the following key operations:
1. Pressing the Intercom key toggles Intercom between on and off.
2. Entering Menu Mode by pressing the Menu key, and then executing "Intercom" can toggle Intercom between on and
off.
Note
The audio input to a Control Head is returned on KRK-15B via KCT-71, and is emitted from the other Control Head.
0
Therefore, only the Mic Line is available as the Modulation Line when Intercom is used, and the audio is not input from
MI2 of the D-sub 25-pin connector.
If audio is received when Intercom is on, the received audio is emitted from Control Head 1 and Control Head 2. The
0
received audio is also emitted from the external speaker connected to each RF Deck.
Intercom turns off if a Zone-channel is changed, the Selected RF Deck is switched, or scanning is toggled between on
0
and off when Intercom is on.
If audio is received while communicating by using Intercom, the Intercom behavior is prioritized, and the received audio
0
is not emitted from the speakers of Control Head 1 and Control Head 2. Also, the received audio is not emitted from the
external speaker connected to the Selected RF Deck.
If audio is received while communicating by using Intercom, the receipt of audio can be confirmed with the lighting of the
0
LED.
When Intercom is on, various commands such as Radio Inhibit/Uninhibit, Radio Check, Remote Monitor (Radio Monitor),
0
and Stun are accepted as usual.
KCH-20R is not equipped with any speakers. Therefore, if KCH-20R is used, KES-5 needs to be connected via KCT-72.
