TIPS
BATTERY LIFE
The Grasshopper™, Locust™, Yellow Jacket™ and Yellow Jacket Plus (fomally called Scorpion), Beetle™, Cricket™, and Cicada
W-LAN receivers use 4 or 5 Ni-MH long-lasting “AA Cells”.
1. Ni-MH batteries do not charge to full capacity the first time they are charged.
2. Ni-MH batteries do not charge to full capacity the first time they are charged after a long period of inactivity. or after a long
period of non-use.
Cause:
When charging Ni-MH batteries for the first time after long-term storage, deactivation of reactants may lead to increased battery
voltage and decreased capacity, (which causes premature termination of charging). Because batteries are chemical products
involving internal chemical reactions, performance deteriorates with prolonged storage. This is normal in Ni-MH batteries.
Resolution:
Ni-MH batteries may not charge to full capacity the first time they are charged, or after a long period of inactivity.
The first-time charge of the Ni-MH Rechargeable Battery Pack should take approximately 2 hours. If the Receiver Dock light
turns green, indicating a full charge, in less than 2 hours, repeat the charge cycle as follows:
First-time Charge:
1. To begin charging, place the instrument on the Charge Dock. Refer to your instrument’s User Guide for details.
2. When the charge light turns green, remove the W-LAN Receiver from the dock and place back on the dock after several
seconds.
3. Repeat steps 1 and 2 three or four times or until the combined charge time is 2 hours.
Subsequent charges of the W-LAN Ni-MH Battery Pack will not require multiple charging cycles unless left uncharged for a long
period of time (greater than 2 months).
In the PocketPC’s OS, choose Settings and then
choose System settings at the bottom. Select the
battery icon for Power Settings to access this
screen. These power settings come unchecked
from the BVS factory to ensure Yellowjacketplus
software runs optimally. Power must remain on
during logging or else data might be corrupted.
NEVER LEAVE THE IPAQ ON FOR EXTENDED TIMES (10 HOURS OR GREATER)
WITHOUT EXTERNAL POWER. ALWAYS SAVE ANY DATA AND THEN TURN OFF
IPAQ (TOP RIGHT POWER BUTTON) WHEN NOT IN USE. NOT DOING SO WILL
RESULT IN DAMAGE TO THE IPAQ’S INTERNAL BATTERY.
NOTE: In order to prevent the Ipaq from freezing when running
YellowjacketPLUS software (therefore rendering the power button use-
less), make sure to:
1. ALWAYS leave the checkboxes in the SETTINGS/SYSTEM/POWER
screen unchecked. Power-save mode will lock up the application due
to the fact that the application is stopped while communicating with the
hardware..
2. Make sure that the battery level on the Ipaq remains above 40%.
The serial card interface may cease to operate when the battery level
is under 40%.
To resolve the freeze, simply press the soft reset button on the bottom of
the Ipaq with the stylus.
