DPSI RV Family Operating Instructions Version 2.1

This principle is repeated until the buzzer has beeped five times
(deactivate all tests). If the missing battery is not attached within three
seconds, no programming is done and the system changes to the
normal operating mode.
The types of batteries are defined as follows:
Buzzer code Battery Type / Programming
1x beep 5 cell battery (NiCad / NiMH)
2x beep 6 cell battery (NiCad / NiMH)
3x beep 7 cell battery (NiCad / NiMH)
4x beep 2 cell LiPo battery
5x beep Deactivate all tests
At delivery, “Battery type No. 4” (LiPo battery) is programmed by
default. When “5 beeps” is selected (all tests deactivated), the DPSI
does not carry out any voltage tests. Therefore, no empty batteries or
other faults are acoustically notified!
Hint:
Two identical batteries must be used at all times (i.e. the same battery type
(NiCad, NiMH or LiPo) and same number of cells). The battery capacity may
vary, on the other hand (even if this is not practical).
Hint:
If using LithiumIon batteries (LiIon) “battery type 2” is to select (6 NiCd/NiMH
cells). This battery type corresponds to the discharge characteristic of LiIon
batteries best.
For LiFePO4 batteries “battery type 1” (5-cell NiCd) can be programmed. Better
do not rely too much on low voltage warnings for LiFePO4 batteries because this
battery type drops quickly at the end of its capacity. Here responsibility of the
pilot is in order to judge the capacity (flight time) correctly.
