WARNING

Initial visual inspection

After unpacking the equipment, inspect the shipping container and its cushioning material for signs

of stress or damage. If damage is identified, retain the packing material for examination by the

carrier in the event that a claim is made. Examine the equipment for signs of damage; do not connect

the equipment to a supply when damage is present, as internal electrical damage could result in

shock if the equipment is turned on.

WARNING

Electrical hazards (AC supply voltage)

This equipment conforms with IEC Safety Class I, meaning that it is provided with a protective

grounding lead. To maintain this protection the supply lead must always be connected to the source

of supply via a socket with a grounded contact.

Be aware that the supply filter contains capacitors that may remain charged after the equipment is

disconnected from the supply. Although the stored energy is within the approved safety

requirements, a slight shock may be felt if the plug pins are touched immediately after removal.

Do not remove instrument covers as this may result in personal injury. There are no user-serviceable

parts inside. Refer all servicing to qualified personnel.

WARNING

Ventilation

Before switching on the instrument, ensure that ventilation slots are not restricted, or obstructed

with loose material.

Provide clearance of at least 3 cm (1 in) between all sides of the instrument and adjacent surfaces.

A failure to provide adequate clearances increases internal temperatures, possibly reducing the

reliability of the equipment and degrading its performance, or even causing a fire.

Remove the instrument from the carry case before use. Never power up the instrument in the carry

case. If a battery is fitted, always switch off the instrument with the rear-panel rocker switch before

placing the instrument in the carry case.

WARNING

Toxic hazards

Some of the components used in this instrument may include resins and other materials that give

off toxic fumes if incinerated. Take appropriate precautions, therefore, in the disposal of these items.

External power supply

The external power supply of the 2201R Mobile Tester is a safety class I equipment as defined in EN 60950.

Do not try to open the power supply. There are no serviceable parts inside. If the power supply is defective you can

obtain a new one from Cobham (part number 23725/657).

Use the supplied power cord or an appropriate replacement.

Do not replace the power cord with an inadequately rated cord.

The power cord set must be an appropriately rated and approved cord-set in accordance with the regulations of the

country it is used in.

Power supply ratings

Before powering on, ensure that the operating voltage that is permitted for the instrument is the same as your power

source. The external power supply adjusts itself automatically to the applied (permissible) line voltage.

WARNING

Lithium

A Lithium battery is used in this equipment.

As Lithium is a toxic substance, the battery should in no circumstances be crushed, incinerated or

disposed of in normal waste.

Do not attempt to recharge this type of battery. Do not short circuit or force discharge since this

might cause the battery to vent, overheat or explode.

WARNING

Liquid crystal display (LCD) module

The liquid crystal substance within the display panel used in this instrument is a toxic substance. If

the display panel is damaged and any of the liquid crystal substance leaks out, do not allow it to

come into contact with your mouth. If the substance comes into contact with your skin,

immediately wash the affected areas with soap and water, and seek medical advice.

The display illumination is produced by a cold cathode fluorescent tube (CCFT). This contains a small

amount of mercury gas, which is a toxic substance.

The display panel is made of glass. Therefore, do not subject the instrument to mechanical shocks

that might cause fractures.

Do not dispose of these modules, or any part of them, in domestic waste. Use only approved waste

disposal methods.

About the 2201R Mobile Tester

Cobham’s 2201R Mobile Tester addresses the specific features and frequency bands introduced by GSM-R, the

railway communication system based on GSM. The specific design of the 2201R’s RF front end allows direct

connection to GSM-R device types, including high-powered Power Class 2 radios.

The 2201R Mobile Tester is a test instrument for GSM-R mobile devices and portable GSM-R Cab Radio systems for

rail companies. Devices can be tested by simulating call features specific to the GSM-R, such as Voice Group Call

Service (VGCS) and Railway Emergency (REC) calls.

The 2201R Mobile Tester meets the requirements of installation teams, maintenance teams, service centers and

manufacturers of GSM-R terminals who need to perform fault analysis and diagnosis. It performs fast and accurate

RF measurements and offers a full range of features, including voice, data and the SMS testing functions for GSM-R

mobile handsets and cab radios. The 2201R supports both GSM and GSM-R phones and devices.

The 2201R can simulate group calls (VGCS) at various priority levels. These include emergency calls based on group

calls, to verify the performance of cab radios and peripherals such as optical and acoustical alarms. These tests ensure

proper performance of the overall radio system and help to verify safety function in an emergency case.

The 2201R lets you validate the correct operation of GSM-R radios through an easy-to-use interface, which allows

the setting of the group ID and priority level, used when performing a voice group call (VGCS). Depending on the

group ID and priority level, this will either be a standard call or an emergency call.

The 2201R allows voice group calls to and from the mobile to validate bi-directional communication. For the

mobile-originated call, the tester decodes the group ID and priority level, while performing measurements.
