Crestron ST-BTP Rechargeable Power Pack
NOTE: The ST-BTP contains a NiCad battery. When the unit can no
longer retain a charge, it must be recycled or disposed of properly. Refer
to the recycle label on the unit for disposal information.
To prevent short-circuiting, use care when handling the ST-BTP. NiCad
cells have extremely low internal resistance and discharge at high current
levels when shorted. As a result, the high temperatures can damage the
rechargeable power pack and may cause personal injury. Avoid
accidental shorting from uninsulated workbenches, tools, bracelets, rings,
and coins.
Storage
The ST-BTP can be stored in a temperate dry place (removed from the
touchpanel and docking station) indefinitely without significant
irreversible degradation in its performance. The self-discharge rate is a
function of temperature and internal resistance. High temperature storage
reduces charge retention. Best results occur if the ST-BTP is stored at an
average temperature of 68° to 86°F (20° to 30°C). After an extended
storage, initiate a few charge/discharge cycles to restore full capacity.
Recharge the ST-BTP prior to use.
Installation
The unique design of the ST-BTP prevents it from being installed
improperly. The rechargeable power pack only fits one way into the
battery compartment of the touchpanel.
The ST-BTP can be installed into a number of Crestron wireless
touchpanel models. The ST-1550C and its related family members (i.e.,
STX-1550C & STX-1550CW) are the most common models. These
models have a similar overall shape and battery compartment location.
Therefore, the illustration on the next page shows the ST-BTP properly
seated in the ST-1550C, as an example. Complete the following steps to
install.
