internal clock battery

Daniel Portugal All Messages By This Member #248558 Do RMC3s, CP3s, etc. and 4-series have a battery for keeping internal clock?
Steve Kuehn All Messages By This Member #248559 I cannot speak for all Crestron products, but at least my CP3 has a CR2320 3V Lithium coin battery in it.? As a side note, I don't every recall a Crestron processor losing time completely it doesn't have power.? But without an Ethernet connection or ntp disable, the clock will eventually drift off time.

Without an NTP reference the drift can be substantial even with a battery. ? -- Lincoln King-Cliby Commercial Market Director Sr. Systems Architect \| Crestron Certified Master Programmer (Diamond) ControlWorks Consulting, LLC Direct: (+1)440.771.4807 \| Cleveland: (+1)440.449.1100? \| Boston: (+1)508.695.0188 \| DC: (+1)202.381.9070?

Rob All Messages By This Member #248573 The DMPS3-4K-350C-AirMedia that I took apart yesterday had a Panasonic coin cell battery in it. It also had an extra machine screw in it which was loose and rattling around, hence the reason why I took it apart.
Rob All Messages By This Member #248588 Edited Confirming to be a Panasonic CR2032 coin cell with positive+ facing up in the unit I just took apart to extract more loose machine screws.
