6, Installation and Connection
The Condition for Installation
The terminal asks for 110- 220V AV power supply. It must be installed in the area where the GSM
network can cover. The strength of the signal can affect the quality of voice.
1. Screw off the screws that are on the back of the terminal, Insert SIM card for every Sim card
holder, and then tighten the screws.
2. Install antenna. In order to ensure the quality of voice, antenna must be put beyond 1.5 from
the telephone and terminal.
3. On end of the telephone line connects to the “Phone” port of the terminal, the other end
connects to telephone.
4. “Power” port connects to power adapter that is connected to 110-220V AC power supply.
The Installation for Connecting to PSTN &Ordinary Telephone
The Sketch for connecting to PSTN And Ordinary Telephone set.
Draw your attention: Because there are many types of ordinary telephone and their electric
parameters are different. In order to avoid mutual disturbance between telephone and terminal
and affect voice quality. The distance between telephone and terminal is 1.5m at least.
