Interactions between Control Heads
Your service provider can connect to one transceiver either two the same control heads (two Remote
Ethernet Control Heads, or two Telephone Style Control Heads), or two different control heads (one
Remote Ethernet Control Head and one Telephone Style 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.
If control heads are different, when you operate on one control head, the second one displays screen
saver.

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.
• The inactive control head displays Link Error and shows Link Error display (if power is available).
Turning on/off one control head results in simultaneous turning on/off the second control head.
Audio Accessories
Depending on a call type, voice can be routed to control heads and audio accessories connected to
them in different ways.
During an outogoing group call, voice can be heard either on one control head or on both control heads
(depending on your service provider’s settings).
During an incoming group call, voice is always heard on both control heads. However, if two
accessories are connected to one control head (to the front and the rear connector), voice is
transferred through only one of them, the one with higher priority. Priority is following (from the
highest): handset (must be off-hook), HSM, external speaker.
Private calls are always transferred to the control head that receives a call.
