DCLOTL (DC Line Operated Transmit Light)
The DCLOTL indicates that a parallel-connected desk set is transmitting by illuminating the
TRANSMIT
LED. This indicates that the wire line to the base station is busy.
When dc voltage is detected on the wire lines connected to the desk set, the DCLOTL prevents
simultaneous transmissions over the control lines. This feature is enabled/disabled by SWA-7. For more
information, see the switch setting table on page 7.
Initiating Calls
Before initiating a call, press the
MONITOR
button to verify that the radio channel is clear. To initiate a
call, press the
TRANSMIT
button or the handset push-to-talk (PTT) pressbar. The
TRANSMIT
LED
illuminates when transmitting.
Always allow a short delay before speaking to allow time for the radio channel to be established. The
TRANSMIT
button or handset PTT bar must be held down while talking to the radio user and released to
listen. When the transmission is completed, the
TRANSMIT
LED extinguishes and the desk set returns to
the receive mode.
Receiving Calls
When power is first applied, the desk set is in the receive mode, allowing receive audio to be heard
through the speaker or handset. The desk set is always in receive mode unless the user presses the
TRANSMIT
or
IC
buttons.
The desk set contains an internal or local speaker and a handset speaker, which operate as follows:
 When the handset is in the cradle, or on-hook, receive audio is heard on the local internal speaker.
 When the handset is off-hook, receive audio is routed to the handset.
Handset Transmit
Using the handset is recommended when the desk set is located in noisy surroundings. Press the handset
PTT bar or
TRANSMIT
button and speak into the handset microphone.
Transmit From Internal Microphone
Use the internal microphone only in low noise environments. The handset must be on-hook for the
internal microphone to operate. Press the
TRANSMIT
button and speak in the direction of the internal
microphone. For the best transmit audio quality, maintain a distance of about 12 to 18 inches from the
microphone.
