Docking Station/Charger Crestron ST-DS

••
Docking Station/Charger: ST-DS
Operations Guide - DOC. 5738A
Method 3: ST-BTP Installed in an Active Touchpanel
This method is identical to method 2, except that the touchpanel is active (ON)
while charging. As a result, the time to fully charge a discharged ST-BTP can take
up to three hours.
Fully Discharging the ST-BTP
Due to the memory effect of nickel-cadmium (NiCad) cells, Crestron recommends
that the ST-BTP be fully discharged for every 25 charge/discharge cycles. The
ST-BTP can be fully discharged while in the touchpanel. A button to fully discharge
the touchpanel should be available within a designated screen design. This button
has a special software identity (reserve join number) and can be recreated and
programmed onto any page in the touchpanel project. Consult your Crestron dealer
if this feature cannot be located.

ST-DS is in "charge 
pending" mode.
The rechargeable power pack is either too hot/cold 
or has extremely low voltage. No action is 
necessary. The ST-DS monitors the ST-BTP and 
begins a fast charge as soon as conditions are 
favorable. Charging occurs when the ST-BTP 
temperature is between 59-86 °F (15-30 °C).
Red CHG and ST-DS has
Properly position the ST-BTP in the ST-DS cavity.
