Recharging the Battery
NOTE . To assure proper operation under all conditions, always plug
the AC adapter into the RFM 150 before connecting to the AC power
source.
1. Connect the supplied Tektronix AC adapter to the RFM 150
power input. Connect the adapter plug to an appropriate
AC power source. The instrument will emit two short beeps, and
the screen will remain blank. If this does not happen, check your
power source. (See Table 4–7 on page 4–6 for power source
requirements).
2. With the instrument power off, allow the RFM 150 to charge for
eight hours. Note that the battery will not charge if the instrument
is turned on or in the sleep mode.
3. Turn the instrument power on, and press the HELP key. The
percent of remaining battery charge is indicated in the upper right
portion of the help screen. The reading after a full eight hour
charge should be 99% or 100%.
4. If the operating time from a full charge seems significantly
shortened, the battery should be replaced, using the procedure on
page 6–13.
