Chapter 3. Using Your APS3
3.2
Opening and Closing the Charging Case
The APS3 device comes in a plastic charging case that is used for storing it when not in use and
for charging the rechargeable battery in the APS3 device (see “Using the Rechargeable Battery” on
page 3.25). The APS3 device should be stored in the sealed charging case when not in use.
The charging case is air-tight. After air transport it may be necessary to relieve the pressure
differential in order to open the case. To do so, loosen the pressure relief vent screen until air
enters the case. Then re-tighten the screw.
To open the charging case:
1. Loosen the captive screws on the top of the case (see Figure 3.1).

2. Lift the lid of the charging case using the captive screws.
To close the charging case:
1. Lower the lid.
2. Tighten the captive screws until the top of the case is secured. (see Figure 3.1)
