Power Source

DESCRIPTION

SIP manpack radios, including those in dismount kits of

AN/VRC-88A/D and AN/VRC-90A/D configurations, require batteries

for their main power source and hold-up (memory retention) function.

This paragraph offers users of SIP radios with general guidelines

regarding the number of hours of a particular type usage each battery

is expected to provide. These times are based on computations as well

as experience. Actual battery life will vary depending upon how long

the battery has been in storage and the temperature at the time the

battery is being used. Even so, these times offer you a basis for

planning your battery requirements.

ESTIMATED BATTERY LIFE USING BA-5590, RFPWR AT HI SETTING*

Table 2-5. Manpack Radio Main Power

Use of HRCRD reduces times shown by approximately one-half hour.

Represents 9 minutes of receiving and monitoring to every 1 minute of transmitting.

*** Represents 2 minutes of receiving and monitoring to every 1 minute of transmitting.

**** In STBY, RT draws power from main battery not the HUB.
