(Note 1) To keep overall performance of the MM-5100 Wireless Modem such as RF and audio, the
power supply should meet some electrical characteristics. For best performance, good supply
regulation is required because the most important characteristic of power supply is supply voltage
stability.
(Note 2) If supply voltage falls below 5.7v, the MM-5100 Wireless Modem will automatically power
down and then restart once voltage increased to 6.0v. The MM-5100 Wireless Modem is protected
against voltage over 36V.
(Note 3) If the over-voltage is continuous, the protection is guaranteed by the fuse.
In cases of transient-voltage or surge current, protection is guaranteed by TVS(Transient Voltage
Suppressor) device.
