Front Panel
The front panel is designed with two groups of LEDs that display modem activity and signal strength. The first group of LEDs
display modem activity, such as transmit and receive data, carrier detection, link status, terminal ready indicating connection to
the pc, and the power indicator. The three Signal LEDs display the signal strength level of the wireless connection. The SIM
door on the right side of the modem provides access to the SIM card holder for those configurations.
LEDs
*To be accurate, the AT^SSYNC command must be set to 1 so that factory default LED timings are used.
Back Panel
Your back panel will differ only if you have purchased the optional GP model that has an additional connector for a GPS
antenna. The GPS antenna connector is located between the power connector and the RS-232 connector. The far right
connector is for the wireless antenna.

Transmit Data: Lit when modem is transmitting data. Not valid while in USB mode.
Receive Data: Lit when modem is receiving data. Not valid while in USB mode.
Carrier Detect: Lit when data connection has been established. Not valid while in USB mode.
Link Status LED is dependent on the model:
-E1 version* (When AT^SSYNC=1)
Permanently off. ME is in one of the
following modes: Power Down mode,
Airplane mode Non-Cyclic Sleep mode with
no temporary wake-up event in progress.
600 ms on/600 ms off
Limited Network Service: No SIM card
inserted or no PIN entered, or network search
in progress or ongoing user authentication, or
network login in progress.
75 ms on/3 sec off
Idle mode: The mobile is registered to the
GSM network (monitoring control channels
and user interactions). No call is in progress.
75 ms on/ 75 ms off/75 ms on/3 sec off
One or more GPRS contexts activated.
500 ms on/ 25 ms off
Packet switched data transfer in progress.
Permanently on
CSD call – Connected to remote party.
Terminal Ready: Commonly referred to as “Data Terminal Ready”, this is a readiness signal from the PC.
Power: Indicates presence of DC power when lit.
GPS: If a valid GPS signal has been received, the PWR/GPS LED will blink at 1 second ON, and 0.5 second OFF.
ALL OFF – Unit is off, not registered on a network or has an extremely weak signal (0 < = RSSI < 6).
1 Bar ON – Very weak signal (7 < = RSSI < 14)
1 and 2 Bars ON – Weak signal (15 < = RSSI < 23)
1, 2, and 3 Bars ON – Good signal (24 < = RSSI < 31)
If GPS signal is invalid, the PWR/GPS LED will be on solid.

LED Indicators
Off state. Modem is off (not
ready) or in download mode.
-G2 and -C1 versions
Continuous “on” state
indicates that the wireless
modem is not registered on the
network.
Flashing states:
200 ms on / 2 sec off
Indicates registration on
network.
200 ms on / 600 ms off
Indicates it is registered on a
network and communication is
in progress.
MTCMR-xx-GP (GPS antenna)
MTCMR-C1, -EV2
-H4 and -EV2 versions
Continuous “on” state
indicates that the modem is
powered on, and registered on
the network.
Slow flashing state (5
seconds) indicates the modem
powered on and searching for
registration on a network.
Fast flashing state (0.3
seconds) indicates the modem
is transmitting or receiving.
Off state. Modem is off (not
powered).
