Troubleshooting

Time Setting

■ The current time setting is off by hours.

Your Home City setting may be wrong (page E-12). Check your Home City setting and
correct it, if necessary.

■ The current time setting is off by one hour.

You may need to change your Home City’s standard time/daylight saving time
(DST) setting. Use the procedure under “Adjusting the Digital Time and Date
Settings” (page E-15) to change the standard time/daylight saving time (DST) setting.

World Time Mode

■ The time for my World Time City is off in the World Time Mode.

This could be due to incorrect switching between standard time and daylight saving
time. See “To specify standard time or daylight saving time (DST) for a city” (page E-20)
for more information.

E-38

To change the illumination duration

1. In the Timekeeping Mode, hold down A until the seconds start to fl ash. This is

the setting mode.

2. Press C nine times so the illumination duration setting mode is on the display.

3. Press D to toggle the illumination duration between 1.5 seconds (

3seconds (

4. After the settings are the way you want, press A to exit the setting mode.

Illumination Precautions
