PowerSafe Telemetry Receiver Manual

Installation

1. Find a secure mounting location on a mounting tray or bulkhead

2. Self tapping mounting screws are provided to use the integrated mounting

tabs and grommets.

3. We recomend drilling a pilot hole for the mounting screws to prevent the

mounting surface from splitting.

TIP: If the screw is threading into a soft material such as balsawood,

harden the threads with thin CA before ﬁnal mounting.

4. It is not neccesary to compress the grommets tightly. Use a 2mm hex driver

to install the mounting screws so the grommets are gently compressed.

5. Secure the remote receivers so they are perpendicular from each other and

located away from conductive materials. It is best to locate the remotes in

different parts of the aircraft for best performance.

TIP: If you have telemetry link performance issues, inspect and/or relocate

the SPM4651T remote receiver to optimize performance in your aicraft.

NOTICE: Do not cut the antenna wire or allow it to kink on the SPM4651T

remote receiver. The last 31mm of the wire is the active portion of the

antenna. The coaxial wire leading up to antenna will be damaged if it is cut

or kinked.

6. Mount the soft switch on the side of your aircraft and insert the switch plug

in the port marked SWITCH.*

Soft Switch

*The PowerSafe receiver uses a speciﬁc switch. Conventionally wired switches

are not compatible with the PowerSafe receiver.

• The Soft Switch is a failsafe switch, it opens the circuit to power ON the

receiver. If a switch failure occurs during operation, the system will fail to

the ON position.

• The trickle current when the receiver is powered OFF is negligible and

will not affect the charge status during a ﬂying session. However, always

unplug the batteries from the receiver at the end of a ﬂying session.

• Connect the lead labeled Switch into the receivers Switch port. The

second lead labeled LED PWR can be connected to any of the receiver

ports that are powered to provide power to the switches LED which

can be used to see at a glance that the system is powered on from the

switch. The switch LED is optional, if not used simply secure the LED

PWR lead.

NOTICE: Failure to unplug the receiver batteries after a ﬂying session will

result in a trickle current that will slowly drain the receiver battery. An over-

discharged battery should never be recharged.
