Philips EM43 manual Changing Batteries, Battery life, Low Battery Indicator

Batteries

The EM43 uses 8 AA cells for power. The EM43 will accept a variety of AA cell battery types (or chemistries):

•Alkaline (such as Duracell or Energizer)

•Oxy-nickel hydroxide (such as Panasonic Oxyride)

•Lithium (such as Energizer e2)

•NiMH or NiCad rechargeable

Caution: Do not use mixed battery

types. This can cause battery leakage and damage to the EM43.

Changing Batteries

To change the cells, release the latches on the either side of the monitor and separate the two halves where you’ll find the batteries readily accessible.

Caution: Always install 8 new, fresh batteries when replacing spent ones. Using new and spent batteries together can lead to leakage and damage.

Caution: Verify the batteries are installed in the holder in the proper direction. Reversed cells may leak and cause damage.

When closing the EM43 housing, perform a routine inspection of the o-ring for any foreign material or damage. Replace if necessary and clean the o-ring groove before installing the new o-ring. Refer to the Gates “Housing Care and Maintenance Guide” for more information.

Caution: Do not lubricate the large orange o-ring! It is a special silicone o-ring and can be damaged by petroleum-based lubricants.

Battery life

The EM43 will operate for ~9 hours when in HD mode and ~14 hours in SD mode of operation. Battery life will also be affected by battery type, manufacturer, age, temperature and operating mode (SD or HD).

Low Battery Indicator

The EM43 is equipped with a red low battery LED warning light located on the right side of the display. The low-battery LED will give you ~30-60 minutes warning to change batteries. Note that different battery type, manufacturer, age, and temperature will affect the amount of time left when the LED turns on.
