When the unit is turned on, the Power Indicator will illuminate and 

the Network Indicator will flash quickly while the C3 searches for a 

network.  When a network is found, the Network Indicator will flash 

slowly and the Signal Strength Indicators will illuminate based on 

the GSM signal strength. 

If the SIM card is not installed or the SIM card can’t be used, the 

Signal Strength Indicators and Network Indicator will flash quickly.  If 

a connected phone is taken off-hook, a busy signal will be heard. 

Note: If the SIM care is not installed or can’t be used, turn the 

Power Switch to “Off” so that the landline can be used as normal.
