7-Troubleshooting pulseEKKO PRO
98
The receiver and transmitter contain a voltage monitoring circuit that will cause the Power LED on top of
the units to slowly flash when the battery voltage is getting low. When this occurs, batteries should be
replaced as soon as possible. If the batteries are not replaced and the voltage continues to drop, the unit
will eventually turn off.
If the voltage of the discharged batteries is measured some time after they have been changed it will be
higher than 10.2 volts (this is normal). Do not mix charged and discharged batteries and DO NOT attempt
to use discharged batteries a second time.
If a battery has been deeply discharged or left in a discharged condition for some period of time it may not
accept charge immediately when it is connected to the charger (the fast charge LED will not light). If the
fast charge light does not come on within 6 hours the battery should be considered damaged and
discarded.
Do not assume that a battery that is still charging after 8 hours is nearing the end of its
charge cycle. Typical charging time for an empty battery is 12 hours from start of fast
charge. When charging a depleted battery it is normal for the charge light to go out after
6-8 hours. The charger has gone into trickle mode only and the battery must remain in the
charger for the minimum 12 hours required.

Ensure that the batteries are fully charged before storing. If practical, store the batteries in a cool place, 10
C (a refrigerator is ideal), but make sure the temperature is not likely to drop below -30 C or the electrolyte
may freeze and possibly split the case.
7.1.4 Testing Transmitter and Receiver Batteries
If you are experiencing reduced operation time with either your pulseEKKO PRO Receiver or Transmitter
the problem will be the result of a damaged 12 V battery or a poor battery connection in one of the battery
compartments.
