Do not touch the contact surfaces of the battery. The battery must be mounted in a correct way.
Reversed polarity will cause a loss of calibration data or memories.
The FAVOR AIR will not loose its calibration data or the logbook and history memories, if the
instructions of this manual are carefully followed.
The altitude mode will remain as it was before, whereas the time and date will be zeroed.
Battery Replacement
The battery and the buzzer are located in the back of the FAVOR AIR in a separate compartment.
To change the battery, do as follows:
1. Disassemble the computer console, including the back cover, as described in Section 5.2,
"Assembly and Disassembly". You do not need to remove the high pressure hose.
2. Thoroughly rinse and dry the computer.
3. Open the securing ring of the battery compartment lid by pushing it down and turning it
counterclockwise. If finger power is not sufficient, you may use a pencil or screwdriver. Lay the pencil or
screwdriver over the ring into the slots and turn the ring with it.
4. Remove the ring.
5. Carefully remove the lid with the beeper attached to it. The lid can be removed by pressing with your
finger on the outermost edge of the lid while at the same time pulling with your nail at the opposite side.
Do not use sharp metal objects as they might damage the O-ring or the sealing surfaces.
6. Remove the O-ring and the colored battery holder.
7. Note the polarity of the battery. Carefully remove the old battery and wait at least 1 minute before
installing the new one.
Do not damage the electrical contacts or the sealing surface.
8. Check for any traces of flooding, particularly between the beeper and the lid, or for any other damage.
If any moisture or water are observed, refer to Section 5.4, "Battery Compartment Inspection". Also
check the condition of the O-ring, because a defective O-ring may indicate sealing or other problems.
Dispose of the old O-ring, even if it seems to be in good condition.
9. Check that the battery compartment, battery holder and lid are clean. Clean if necessary. Fresh
water is allowed, provided that you dry everything properly before the reassembly. Inspect the gold
plated battery contacts for corrosion and clean them if needed.
CAUTION!
DO NOT USE SOLVENTS OR CLEANING AGENTS FOR THE CLEANING;
THEY MAY DAMAGE THE FAVOR AIR.

check the startup functions. If the displays are not correct, remove the battery again, wait at least 1
minute, re-install the battery and activate the FAVOR AIR again.
If the displays still are not correct, or if there is a permanent LOG-display on the LCD, the FAVOR AIR
has lost its calibration data. Please, return the FAVOR AIR to Suunto for recalibration.
11. Reinstall the battery holder in its correct position.
12. Check that the O-ring is clean, undamaged and treated with silicone grease. Mount the O-ring
