Problem
Possible Cause & Solutions
Command Center will
not power on:
• Check wires for voltage. Voltage should be 28vdc.
• If no voltage is detected, confirm you are connected to the DKP interface on the
Distribution Module.
• If you have 48vdc, you are incorrectly connected to an SLT interface.
Phones will not call out: • Check wires for voltage. Voltage should be 48vdc.
• If no voltage is detected, confirm you are connected to the SLT interface on the
Distribution Module (some SLT interfaces only use the blue and orange pairs).
• If you have 28vdc, you are incorrectly connected to the DKP interface.
• Make sure you dial any access digit that may be required to dial out of the building.
Phones will make
internal calls but not
external calls:
• Check that the phone line is connected to the correct interface on the Distribution
Module.
• Verify the phone line by making sure it has 48-52vdc on the line and use an analog
phone to verify you are able to call in and out.
Insufficient volume on
phones:
• To adjust the volume on 2100 Series SmartPhones, turn the VR1 potentiometer.
• To adjust the volume on 2400 Series Phones, use the VOL key.
Light continuously blinks
on button for phone:
• The phone is not properly hung up. Lift the Command Center handset, select the
blinking light, then hang up the handset.
Lights periodically blink
on Command Center:
• This indicates that the phone is doing a phone line check. This is a normal function of
the system and no action is needed.
• To disable this function, refer to the 2100 Series SmartPhone Programming Guide.
Message won’t stop
playing:
• For a 2400 Series Phone, verify that the answering party is pressing the
#
key 4 times
AFTER the beep.
• Verify the verbiage in the message includes instructions on how to stop the message.
• Message can only be stopped during the 3 second gap after the first message ends and
before the second message begins.
Calls won’t forward out:
• Verify call forwarding has been set up on the Command Center.
• Verify the Command Center can place a call out by lifting the handset, dialing
9
, then a
phone number. If a message shows up on the Command Center screen saying, “All
Trunks Busy”, the system does not have an active phone line connected to it.
• Verify dialing string for forwarding number.

corner of the Command
Center won’t stop
blinking:
• A blinking light indicates a missed call.
• To clear missed calls, click the button under “LOGS” on the Command Center
