Note the following information required by Underwriters Laboratories: Underwriters Laboratories, Inc.

Underwriters Laboratories Inc.(“UL”) has not tested the performance or reliability of the Global Positioning System

(“GPS”) hardware, operating software or other aspects of this product. UL has only tested for fire, shock or

casualties as outlined in UL’s Standard(s) for Safety. UL60950-1 Certification does not cover the performance or

reliability of the GPS hardware and GPS operating software. UL MAKES NO REPRESENTATIONS, WARRANTIES OR

OF THIS PRODUCT.

Device Reset

For the -B02 models, reset is connected to the 3G_ONOFF signal. Refer to the 3G_ONOFF topic for functionality.

Powering Down Your Device

CAUTION: Failing to properly power down the device before removing power may corrupt your device's file

system.

To properly power down your device, use the following sequence or pull 3G_ONOFF signal low:

1. Issue the AT#SHDN command.

2. Wait 30 seconds.

3. Power off or disconnect power.

Note: If you send AT#SHDN and do not remove power AND the 3G_ONOFF line is high, the control chip on the

device turns the radio back on after 60 seconds.

Power Measurements

Multi-Tech Systems, Inc. recommends that you incorporate a 10% buffer into your power source when determining

product load.

Note:

The following notes apply to the following tables.

Tx Pulse: The average peak current during a GSM850 transmission burst period or HSDPA/LTE

connection. The transmission burst duration for GSM850 can vary, depending on what transmission

scheme is being deployed (GPRS Class 8, Class 10, GSM, etc.).

Maximum Power: The continuous current during maximum data rate with the radio transmitter at

maximum power.

Inrush Charge: The input current during power up, or a reset.
