added on the signals connected to the SIM interface to prevent any damage from
electrostatic discharge.
The SIM uses five SIM signals, namely:
• SIM-VCC, which is the SIM power supply
• SIM-RST, which is reset
• SIM-CLK, is clock
• SIM-IO, as the I/O port
• SIM-DET, for SIM detection
Refer to the following table for the electrical characteristics of the SIM interface.

• External DC power supply connection with voltage from 4.75V to 32V
• Serial link (RS232) interface
Figure 2-3: Pin Assignment of the 8-pin Micro-Fit Connector
Customers who have previously purchased GL7500 and GL7600 devices should note that
the Y cable (with the 8-pin micro-fit connector to serial/power) included with those older
devices is not compatible with GL7605 and GL7611 devices.
Using a GL7500/GL7600 Y cable with a GL7605/GL7611 will result in significantly higher
power consumption. It is recommended that customers use the cables included with the
GL7605/GL7611 device, or another customer-sourced option following the described
wiring.

6.1 Consumption Measurement Procedure
This chapter describes the procedure for consumption measurement which is used to
obtain the modem's consumption specifications.
The modem consumption specification values are measured for all operating modes
available on this product. For more information about the different operating modes, refer
to Operating Modes.
Consumption results are highly dependent on the hardware configuration used during
measurement and the following chapter describes the hardware configuration settings
that should be used to obtain optimum consumption measurements.
6.1.1 Hardware Configuration
The following hardware configuration includes both the measurement equipment and the
modem.
6.1.1.1 Equipment
Three devices are used to perform consumption measurement:
• A communication tester
• A current measuring power supply
• A computer, to control the modem and to save measurement data

6.3 Power Consumption Values
These consumption values were obtained by performing measurements on samples at a
temperature of 25°C with the assumption of a 50Ω RF output.
Three DC inputs (DCIN) were used to measure the consumption: VinMIN (4.75V), VinTYP
(12V) and VinMAX (32V). Both the average current and maximum current peaks were
also measured.
Note that power consumption performance is also software related. .

A.3 Safety Recommendations (for information
only)
For the efficient and safe operation of your wireless device, please read the following
information carefully.
A.3.1 RF Safety
A.3.1.1 General
Your wireless terminal is based on the 3GPP standard for cellular technology. The
standard is spread all over the world. It covers Europe, Asia and some parts of America
and Africa. This is the most used telecommunication standard.
Your wireless terminal is actually a low power radio transmitter and receiver. It sends out
and receives radio frequency energy. When you use your wireless application, the cellular
system which handles your calls controls both the radio frequency and the power level of
your cellular modem.
A.3.1.2 Efficient Terminal Operation
For your wireless terminal to operate at the lowest power level, consistent with
satisfactory call quality:
If your terminal has an extendible antenna, extend it fully. Some models allow you to place
a call with the antenna retracted. However, your wireless terminal operates more
efficiently with the antenna fully extended.
Do not hold the antenna when the terminal is " IN USE ". Holding the antenna affects call
quality and may cause the modem to operate at a higher power level than needed.
Rev. 2.1 September 2022
59
41114368
Product Technical Specification
A.3.1.3 Antenna Care and Replacement
Do not use the wireless terminal with a damaged antenna. If a damaged antenna comes
into contact with the skin, a minor burn may result. Replace a damaged antenna
immediately. Consult your manual to see if you may change the antenna yourself. If so,
use only a manufacturer-approved antenna. Otherwise, have your antenna repaired by a
qualified technician.
Use only the supplied or approved antenna. Unauthorized antennas, modifications or
attachments could damage the terminal and may contravene local RF emission
regulations or invalidate type approval.
A.4 General Safety
A.4.1 Driving
Check the laws and the regulations regarding the use of cellular devices in the area where
you have to drive as you always have to comply with them. When using your wireless
terminal while driving, please:
• give full attention to driving,
• pull off the road and park before making or answering a call if driving conditions so
require.
A.4.2 Electronic Devices
Most electronic equipment, for example in hospitals and motor vehicles is shielded from
RF energy. However, RF energy may affect some improperly shielded electronic
equipment.
A.4.3 Vehicle Electronic Equipment
Check your vehicle manufacturer representative to determine if any on-board electronic
equipment is adequately shielded from RF energy.
A.4.4 Medical Electronic Equipment
Consult the manufacturer of any personal medical devices (such as pacemakers, hearing
aids, etc.) to determine if they are adequately shielded from external RF energy.
Turn your terminal OFF in health care facilities when any regulations posted in the area
instruct you to do so. Hospitals or health care facilities may be using RF monitoring
equipment.
Rev. 2.1 September 2022
60
41114368
A.4.5 Aircraft
Turn your terminal OFF before boarding any aircraft.
• Use it on the ground only with crew permission
• Do not use it in the air
To prevent possible interference with aircraft systems, Federal Aviation Administration
(FAA) regulations require you to have permission from a crew member to use your
terminal while the aircraft is on the ground. To prevent interference with cellular systems,
local RF regulations prohibit using your modem while airborne.
A.4.6 Children
Do not allow children to play with your wireless terminal. It is not a toy. Children could hurt
themselves or others (by poking themselves or others in the eye with the antenna, for
example). Children could damage the modem, or make calls that increase your modem
bills.
A.4.7 Blasting Areas
To avoid interfering with blasting operations, turn your unit OFF when in a « blasting area
» or in areas posted: « turn off two-way radio ». Construction crew often use remote
control RF devices to set off explosives.
A.4.8 Potentially Explosive Atmospheres
Turn your terminal OFF when in any area with a potentially explosive atmosphere. It is
rare, but your modem or its accessories could generate sparks. Sparks in such areas
could cause an explosion or fire resulting in bodily injuries or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked.
They include fuelling areas such as petrol stations; below decks on boats; fuel or chemical
transfer or storage facilities; and areas where the air contains chemicals or particles, such
as grain, dust, or metal powders.
Do not transport or store flammable gas, liquid, or explosives, in the compartment of your
vehicle which contains your terminal or accessories.
Before using your terminal in a vehicle powered by liquefied petroleum gas (such as
propane or butane) ensure that the vehicle complies with the relevant fire and safety
regulations of the country in which the vehicle is to be used.
Warning: The device should not be in durable use within 20 cm of the human body
