MFJ-226 Graphical Antenna Impedance Analyzer
6 Version 1A 1R02
POWERING THE MFJ-226
The MFJ-226 requires two (2) good quality AA batteries. The battery
tray door is located on the back of the analyzer case near its base.
Press and slide the lid down to expose the tray.
You may use alkaline non-rechargeable or NiMH rechargeable cells.
Note that NiMH cells require an external charger (the analyzer does
not have one built-in). For longest life, use fresh premium-quality cells
from the same manufacturer. Carefully observe polarity during
installation and never remove batteries while the unit is powered up.
Abruptly cutting power can disrupt the unit's normal power-down cycle
and result in memory loss.
The MFJ-226 features a built-in battery indicator that must be set up
for the type of battery you intend to use. See the Settings Menu for
details.
Note the USB port does not power the MFJ-226 or charge batteries.
