message ‘Reading may be inaccurate’. If this occurs, the battery conditioning
procedure described below should be followed to re-establish the upper and lower
limits for the charge indicator.
7.6.1 Battery conditioning
The battery can be conditioned by performing two full discharge/recharge cycles as
follows:
1. Disable the timed Auto Power-off feature in the Power Saving section of the
Preferences menu.
2. Discharge the battery by leaving the ANT-5 switched on with the external power
supply disconnected. The ANT-5 will switch itself off when the battery is fully
discharged.
3. Reconnect the external power supply and check that the battery LED, , is lit.
4. Leave the ANT-5 switched off whilst the battery is charging. An adequate charge
will be reached within 3 hours and the ANT-5 will automatically switch to a trickle
charge mode when fully charged.
5. Repeat actions 2, 3 and 4 for a second discharge/recharge cycle.
6. Re-enable the timed Auto Power-off feature if required.
7.6.2 Replacing the ANT-5 battery pack
If the rechargeable battery pack develops a fault it can be replaced locally in an
appropriately equipped workshop where protection can be provided from
contamination and static discharge. Replacement battery packs can be obtained from
your nearest Acterna Sales Office or Technical Assistance Centre.
The battery pack can be replaced as follows:
WARNING: Static Sensitive.
Note: Replacing the ANT-5 battery pack may unavoidably cause the setup information
under the System and Preferences menus to return to their default settings.
However, data can be retained if an external power supply is connected.
1. Switch off the ANT-5 and disconnect all connections and the external mains power
supply.
2. Invert the ANT-5 so that the underside is uppermost and the front bumper is closest
to you. Take care to protect the screen and keyboard if the ANT-5 is placed on a
hard surface.
