If no selection of alarm time is made, either press the SNOOZE key or the MODE key; or 
wait for automatic timeout to exit the memory alarm mode. 

 

Note: 

The current alarm 1 time viewed on the memory alarm mode can also be selected and stored on 
the current alarm 2 time by pressing ALM2/MIN key. Once this current alarm 2 time has set, the 
current alarm 1 time will automatically replace by the previous alarm 2 time. 

 

Upon exiting the memory alarm mode, the alarm icons (((1))) or (((2))) will be automatically ON, 
indicating that the Alarm 1 or Alarm 2 is active. 

 

BACK-LIGHT 

The back-light is automatically switched ON when any keys are pressed. The back-light will be 
switched on for approximately 2 seconds before automatically switching OFF. However, if any of 
the keys are pressed and held down, then back-light will remain ON constantly until the key is 
released. 

 

REPLACING BATTERIES 

 

  For optimum running accuracy, batteries should be replaced at least once a year or when the 

LCD contrast becomes dim or unclear. 

 

  Immediately remove all low powered batteries to avoid leakage and damage. Replace only 

with new batteries of the recommended size. 

 

Please help in the preservation of the environment and return used batteries to 
an authorized depot. 

 

MAINTENANCE 

 

  Avoid placing alarm clock in areas prone to vibration and shock as these may cause damage 

and inaccurate readings. 

 

  Avoid exposure to sudden changes in temperature such as direct sunlight, extreme cold and 

wet or moist conditions. 

 

  When cleaning the display and casing, use a soft damp cloth only. Do not use solvents or 

scouring agents as they may mark the LCD and casing. 

 

  Do not submerge the alarm clock into water. 

 

  Do not make or attempt to make any repairs to the alarm clock. Return it to its original point 

of purchase for repair by a qualified engineer. Opening and tampering with the alarm clock 
may invalidate its guarantee
