If you have difficulty with the telephones, please try the suggestions below. For customer service, visit our website at

The telephone does not work at all.
Make sure the Cat-5 network cable is plugged into the LAN port of the telephone base and the network wall jack with
Power over Ethernet (PoE).
Make sure the battery is installed and charged correctly (pages 33, 36, 44, 46, 53 and 55). For optimum daily performance, return
the cordless handset to the telephone base, charging base or charging stand after use.
Unplug the Cat-5 network cable from the network wall jack. Wait for approximately 15 seconds, then plug it back in.
Charge the battery in the cordless handset for up to 16 hours.
If the battery is completely depleted, charge the battery for at least 30 minutes before use.
Remove the battery and then install it again. If that still does not work, it may be necessary to purchase a new battery.
Disconnect the telephone base from the network wall jack and connect a different working SIP telephone. If the other SIP
telephone does not work, the problem is probably in the wiring or network server. Check your SIP server settings. Refer to the
SIP Phone Configuration Guide for details.
Make sure the energy-saving charging mode is not activated. If this mode is activated, all telephone functions will be disabled,
except battery charging (page 84).
There is no dial tone.
Try all the above suggestions.
The Cat-5 network cable may be defective. Install a new Cat-5 network cable.
Make sure your network is providing Power over Ethernet (PoE).
Disconnect the telephone base from the network wall jack and connect a different working SIP telephone. If there is no dial tone
on this telephone either, the problem is in your wiring or network server. Check your SIP server settings and refer to the
SIP Phone Configuration Guide for details.
Make sure the initialization and system registration process completes (pages 32 and 42). The speakerphone key blinks twice
every second if there are errors with the initialization and system registration process. Check your SIP server settings. Refer to the
SIP Phone Configuration Guide for details.
Make sure the energy-saving charging mode is not activated. If this mode is activated, all telephone functions will be disabled,
except battery charging (page 84).
I cannot dial out.
Try all the above suggestions.
Make sure there is a dial tone before dialing. It is normal if the cordless handset takes a second or two to synchronize with the
telephone base before producing a dial tone. Wait an extra second before dialing.
A prefix may be required for dialing some internal or external calls. Refer to the SIP Phone Configuration Guide for details.
Check your SIP server settings. If other SIP telephones in your hotel are having the same problem, the problem is in the wiring or
network server. Contact your telephone service provider (charges may apply).
The Speed Dial key does not work at all.
The Speed Dial key may not be properly programmed. Refer to the SIP Phone Configuration Guide for details..
The telephone does not store the last number dialed.
For security, the last number dialed in the REDIAL memory will be automatically cleared after 15 minutes.
The telephone cannot register to the SIP network server.
Make sure your network is providing Power over Ethernet (PoE).
Make sure the initialization and system registration process completes (pages 32 and 42).
If there is an error during the initialization and system registration process, the
/SPEAKER key flashes twice every second.
Disconnect the Cat-5 network cable from the network wall jack and connect it back into the network wall jack with Power over
Ethernet (PoE) to start the initialization and system registration process again.
The LOW BATTERY LED illuminates on the cordless handset.
Place the cordless handset in the telephone base, charging base or charging stand for recharging.
Remove the battery and then install it again. Use it until fully depleted, then charge the cordless handset in the telephone base,
charging base or charging stand for up to 16 hours.
If the above measures do not correct the problem, replace the battery.
