2 Making Handset Ready
In this chapter we briefly describe how to prepare the handset for use, install, and how to insert and charge new
batteries.
2.1 Package - Contents/Damage Inspection
2.1.1 Before the Package Is Opened
Examine the shipping package for evidence of physical damage or mishandling prior to opening. If there is proof
of mishandling prior to opening, you must report it to the relevant support center of the regional representative
or operator.
2.1.2 Contents of the Package
Make sure all relevant components are available in the package before proceeding to the next step.
In principle, every shipped handset unit package/box contains the following items:
•1 x Charger with A/C Adaptor
•2 x Battery, AAA
•1 x Handset Unit, 1 x Battery cover

SME VoIP Handset guide
Proprietary and Confidential Page | 7
2.1.3 Damage Inspection
The following are the recommended procedure for you to use for damage inspection:
1. Examine all relevant components for damage.
2. Make a “defective on arrival - DOA” report or RMA to the operator. Do not move the shipping carton
until the operator has examined it. The operator/regional representative will initiate the necessary
procedure to process this RMA. They will guide the network administrator on how to return the
damaged package if necessary.
3. If no damage is found, then unwrap all the components and dispose of empty package/carton(s) in
accordance with country specific environmental regulations.
2.2 Before Using the Phone
The following are the precautions users should read before using the handset:
2.2.1 Installing the Battery
1. Never dispose battery in fires, otherwise it will explode.
2. Never replace the batteries in potentially explosive environments, e.g. close to inflammable
liquids/gases.
3. ONLY use approved batteries and chargers from the vendor or operator.
4. Do not disassemble, customize, or short circuit the battery
2.2.2 Using the Charger
Each handset is charged using a handset charger. The charger is a compact desktop unit designed to
automatically charge and maintain the correct battery charge levels and voltage. The handset charger is powered
by AC supply from 110-240VAC that supplies 5.5VDC at 600mA. When charging the battery for the first time, it is
necessary to leave the handset in the charger for at least 10 hours before the battery is fully charged, and the
handset is ready for use.
2.2.3 Handset in the Charger
For correct charging, ensure that the room temperature is between 0°C and 25°C / 32°F and 77°F. Do not place
the handset in direct sunlight. The battery has a built-in heat sensor which will stop charging if the battery
temperature is too high.
If the handset is turned off when placed in charger, the handset turns on and shows (shortly) the charging
message “The battery is charging”. After a while the display backlight first dim and then turns off (if demo mode
is not enabled). In this state, the handset will still respond on for example incoming calls.
If the handset is turned on when placed in charger, the display shows (shortly) the charging message “The
battery is charging”. After a while the display backlight first dim and then turns off if unless “Idle Screen Saver” is
switched on.
2.2.4 How to Open Back Cover
1. Press down the back-cover lock and lift the back cover away from the handset.
2. Remove the back cover from the handset.

SME VoIP Handset guide
Proprietary and Confidential Page | 8
2.2.5 How to Replace Battery
Remove the back cover from the handset as showed in section 2.2.4 How to Open Back Cover above. Then
remove the old battery and replace it with a new one.
2.2.6 Handset Serial and IPEI/IPUI Number
The serial number and IPEI/IPUI number of each handset are found either on a label which is placed behind the
battery, or on the packaging label. First, lift off the handset back cover, lift the battery, and read the serial
number.
