If the values and adjustments of the
HAC
are to be main-
tained during the battery change, the power-saving mode should be
switched on before the battery is changed (see chap. 5.3).

Unscrew counter-clockwise the screwed cap on the reverse side
of the computer with the aid of a coin. Note: do not remove the
foil inside the battery case. Remove the old battery and insert new
3-volt lithium battery type CR 2032 with the plus pole (+) facing up
(below the foil). Close screw cap again.
Do not over twist battery cap!
If no characters or unintelligible characters appear in the display
after the battery change, remove battery again, wait 10 sec. and
insert battery again.
Transmitter belt and handlebar bracket:
Unscrew the battery cap (handlebar bracket: on the upper side,
transmitter belt: on the backside) counter-clockwise and remove the
old battery. Fit a new CR2032 lithium battery, with the plus pole (+)
facing up and replace the cap.
Do not over twist battery cap!
Speed transmitter:
Screw off the battery cap counter-clockwise with the aid of a coin.
Remove the old battery and insert a new 12V battery, type 23A,
plus pole (+) facing up. Close the battery cap.
Please do not discard used batteries in domestic waste, but
discard them on your local recycling-point.

attached electrodes. To clean the transmitter belt, wipe it carefully
with a detergent for synthetic fabrics. Do not dry in direct sunlight.

- heart rate receiver is off and must be
activated again (see chap. 5.3)

- skin is too dry/too cold
- malfunction due to electric cables, pace-
makers, etc. after leaving the malfunction
area, the heart rate will be displayed as usual
- distance between HAC 4000 and transmitter
