OPERATING INSTRUCTIONS

3.7 Hot Key Dial Source List
The source for Hot Key Dial Numbers is normally `Phonebook' or `Service Dial Numbers'. For some OEMs it may be a requirement to store these numbers in the EEPROM. When the source is the EEPROM and the telephone software is updated, the source numbers may be lost. Also, if the user changes the source of the Hot Key Dial numbers, it will not be possible to redirect the source back to the EEPROM. However, in the event that an OEM would like the Hot Key Dial source to be stored in the EEPROM, it is unlikely that the user will have the option to change the Hot Key Dial source.

3.10Troubleshooting
The user is given the following information and advised to contact the dealer if the problems persist:
Problem Telephone will not switch on Extremely short battery life for a new battery pack Short battery life for an old battery pack Short battery life for NiMH battery pack The network in use and the condition of the battery pack can affect battery life. The battery pack was worn out. The life of the battery pack is affected by improper charging, this is inherent in all NiMH batteries. Cause Remedy Check that the battery pack is fully charged and correctly connected to the telephone. Avoid areas of poor reception. Ensure batteries are fully charged. Additionally, for NiMH batteries, ensure batteries are also discharged fully before recharging. Replace with a new one. To maintain maximum performance, always use until the Low Battery Warning appears and then fully recharge the battery pack. To revive a Battery Pack, use the telephone until the Low Battery Warning appears and then fully recharge three times. However, if the battery life still is short, the battery pack has eventually worn out. Replace with a new one. Leave to charge for several minutes in temperatures between +5°C and +35°C.

The battery level indicator H does not light when charging Calls cannot be made

If a battery is deeply discharged it will take a short time before there is sufficient power in the telephone to light the battery level indicator H. The telephone is locked. Outgoing calls are barred. The telephone is not registered to a network.

3.13SIM Personalisation
3.13.1 Introduction
SIM personalisation will limit the use of the telephone to a single SIM, a SIM supplied by one Network/Sub-network/Service Provider or a SIM purchased by a company (corporation). If a personalised GD30/GD50 contains a SIM that is from a different source it will display the message "SIM ERROR" when switched on. This personalisation of GD30/GD50 is sometimes referred to as SIM lock or SIM latch.

3.13.2 Testing
To test a personalised GD30/GD50, when the user has not supplied the SIM, a SIM configured for test purposes (e.g. test SIM or soft SIM) should be used. The mobile will recognise that the SIM is for testing purposes only and operate as normal.

3.13.3 Personalisation Function
Personalisation is activated during manufacture and then enabled at a later stage. Enabling/disabling is available by entering a special key sequence immediately after power on. Once the enable/disable menu is shown it is possible to select the type of personalisation. When personalisation is enabled it is only possible to disable it if the mobile contains an illegal SIM and the sixteen digit Control Key (CK) is known. When enabled the CK is withheld from the user and cannot be read, for security reasons. There are two special key sequences to enter the enable/disable menu: Key sequence

TEST AND MEASUREMENT

Calibration of output power on each power level
NOTE: To ensure that the telephone operates within set SAR margins, Panasonic recommends that a power meter capable of measurement to an accuracy of ±0.2 dBm (Hewlett Packard HP8990 or equivalent) is used when calibrating power levels. Use of a less accurate power meter may result in the phone failing to meet SAR standards.

To calibrate the ramping gain, first switch the unit into Test Mode (Section 6.3). This procedure must be followed for all power levels PL5 to PL19, for low, middle and high channels for GSM 900. GSM 1800 shall be calibrated for all power levels PL0 to PL15 for top middle and bottom channels. 1. Set the Channel box controls to Channel 62 at Power Level 14, normal burst modulated with random data as follows: a. Press the down arrow until CHANGE CH <62> is highlighted and then press ENTER. b. Press the down arrow until PL <14> is highlighted. Press the move left arrow until <14> appears in the highlighted field. Press ENTER. c. Press the down arrow until TX DATA is highlighted. Press the move arrow until appears in the highlighted field. Press ENTER.
