Dual Control Head
This feature allows you to use two control heads with one transceiver. The control heads are of equal
importance and have almost identical functionality, the only difference is second PTT installed on the
Telephone Style Control Head.
In Dual Control Head mode, when you press Menu → Setup you can choose between two control
heads: CH1 and CH2. Almost all menu items inside them are common for both control heads, except
for: Set Volume, Accry Setup, and Font Level (provided that control heads are different). These
menu items are configured separately for each control head.
NOTICE: If this feature is enabled by your service provider, appropriate icons appear on the
display.
Check with your service provider default accessory selections and the radio behavior for all types of
calls as each control head can have different setup.
5.5.1
Interactions between Control Heads
Your service provider can connect one transceiver with either one of the following options:
Two Identical Control Heads
Both control heads have identical resolution and soft-key area location. Identical screens are
displayed on both control heads. Only two Remote Ethernet Control Heads (RECH) or two
Telephone Style Control Heads (TSCH) can be used.
Two Different Control Heads
Both control heads have different resolution, soft-key area location, or both. Any combination of
supported control heads can be used. The active screen is displayed on the operating control head
while an idle screen is displayed on the other control head.
You can use both control heads interchangeably for the same activity (for example, writing a
message). If you start an activity on one control head you can continue it on the second, provided that
token is free.
Token is a right to use a key or button for a period of time. If you press a key/button on one control
head, token activates on it, and no one can press anything on the second control head until token time
passes. After you release the key/button, token becomes available again and can be taken over by the
second control head. When token is activated, Key Press Token icon is visible on the display. By
default, token time is set to 3 seconds.
NOTICE: Token does not apply to EMERGENCY button and ON/OFF/END/HOME key. These can be
pressed on both control heads at any time.
5.5.2
Dual Control Head Link
Dual Control Head Link is a connection that occurs when both control heads are properly connected to
the transceiver and can communicate.
When the Dual Control Head Link is established, control heads play a tone and display Dual
Control Head icon. Full functionality is available on both devices.
When one control head cannot connect to the transceiver upon power up, the radio displays Single
Control Head icon and enters Single Control Head mode.
When one control head disconnects from the transceiver during operation:
• The active control head displays Link Error icon.
