Quantum HD 9021 manual LOW Battery Warning

ENGLISH

LOW BATTERY WARNING

If the battery voltage falls below acceptable levels, a beep sounds every 30 seconds and the H symbol appears. From that moment there remains about 1 hour autonomous operation, however the battery should be replaced as soon as possible.

To change the battery turn the screw on the door of the battery compartment in an anti-clockwise direction.

After replacing it (with an ordinary 9V battery IEC 6LF22) close the door, inserting the tag on the door into the slot provided, and turn the screw in a clockwise direction.

Ensure that the instrument is switched off before changing the battery.

FAULTY OPERATION WHEN SWITCHING ON AFTER CHANGING THE BATTERY

If the instrument does not switch on or off after changing the battery, repeat the battery changing procedure, waiting for a few minutes after removing the battery to allow the circuit condenser capacities to be com- pletely discharged, then insert the battery.

Check that the battery you are using is really efficient; sometimes unused batteries have not been recently manufactured so, due to the auto-dischar- ge phenomenon, their voltage level is insufficient for correct operation of the instrument.

WARNING

*If the instrument is not to be used for a long period the battery should be removed.

*If the battery is flat it must be replaced immediately.

*Avoid leakage of fluid from the battery.

*Always use good quality watertight batteries.
