Long-Term Player Storage
The battery packs shall be disconnected in players that will be stored for longer than 3 months.
This is because even when the player is off the battery pack is always powering a “gas gauge” integrated circuit that
determines the state of battery charge. This circuit consumes very little current but over a long period will deplete
the battery. More significantly, typical self discharge of the NiMH battery is approximately 20 percent per month at
room temperature (20ºC) and more at higher temperatures. Store the battery or player with battery in a cool dry
place.
To disconnect the battery pack:
1.
Turn the player over so the bottom is facing up and loosen the two battery panel screws until each spins
freely.
2.
Lift the battery access panel up and away from the player. Set the panel aside.
3.
Lift the battery pack out of the compartment. Set it on the bottom of the housing.
4.
Grasp the two sides of the battery cable connector.
5.
Press the connector release latch down while pulling the connectors apart.
6.
Return the battery pack to the compartment with the connectors positioned as shown in
