2 Operating the Power Supply
This chapter describes how to operate the EPOCH 4PLUS using different power supply
options.
Topics are as follows:
• Using AC Line Power
• Using Battery Power
• Operating Time for the Battery
• Replacing the Battery
• Charging the Battery
• Using a “AA” Alkaline Battery
2.1 Using AC Line Power
AC line power is supplied via the Charger/Adapter (part number EP4/MCA). The EP4-
MCA has a universal AC POWER input, so it operates with any line voltage from 100-120
or 200-240 Volts AC, and with 50 to 60 Hz line frequency.
To use AC line power, follow these steps:
1. Connect the power cord to the Charger/Adapter unit and to an appropriate line power
source.
2. Connect the DC Output power cable from the Charger/Adapter unit to the Charger/
AC Adapter input jack on the right side of the EPOCH 4PLUS.
3. Turn the EPOCH 4PLUS on via the front keypad.
4. Proceed with normal operation.
2.2 Using Battery Power
The EPOCH 4PLUS uses a Nickel Metal Hydride (NiMH) battery pack. An optional AA
Alkaline battery pack is available.
Press [ON/OFF] to power up the unit after the initial status screen. The EPOCH 4PLUS
proceeds to the split screen display.
A battery symbol is always present at the bottom right corner of the display and indicates
the remaining battery charge. A completely filled battery symbol relates directly to the
charge remaining on the battery. A symbol that is half filled means that the battery is 50%
charged. All batteries show some rebound effects, so the initial reading appears higher
than the actual amount. This is temporary; a stable battery reading can be obtained after 1-
2 minutes of operation.
