The Sintra features a battery backup in order to overcome temporary power loss, avoiding a reboot of its ssuboard in case the cryptomat's host location experiences brownouts.
The battery pack recharges on its own when the cryptomat is connected to wall power, however if powering down your Sintra for transport or other reasons, disconnect the battery pack to ensure its ssuboard is fully powered off.
When shipped from our studio, the cable for the battery backup is disconnected. Use the following article to connect or disconnect the battery.
Accessing and connecting or disconnecting the battery pack
IMPORTANT: Before connecting or disconnecting the battery pack, first remove wall power to the cryptomat. Working with interior cabling can present a risk of electric shock.
Open the Sintra's chassis door with your key. Below the validator and dispenser, towards the bottom right side, the backup battery pack is a black metal square affixed to one of the legs of the cryptomat.
Halfway along the cable which connects it to the ssuboard, is a white Molex connector. Carefully connect (or disconnect) this joint.
If the battery pack has a charge, the ssuboard will power up or remain powered on while connected.
If disconnected (with the cryptomat also unplugged from wall power), the ssuboard will subsequently shut down.
