Emplacement Considerations
The MSRY must be placed within the transmission range of the transmitter (2-10 miles). For the
best results place the relay half way between the transmitter and the receiver on flat surfaces, or
at the top of a hill or building.
Battery
The MSRY Relay incorporates two each 4-volt, 4.5-amp hour rechargeable sealed lead-acid
batteries. The batteries are fully charged at Qual-Tron prior to shipment to provide a minimum
of 9 volts.
NOTE: Due to the self-discharge characteristics of this type of battery, it is imperative that they
be charged periodically if placed in storage. Otherwise, permanent loss of capacity might occur
as a result of sulfation. It is recommended that the batteries be charged every 2-3 months using
the supplied PSEC AC/DC battery charger to prevent permanent damage to the battery. The
PSEC AC/DC charger (13D0229-1) provides a 12-volt, 1.7-amp input. Use only the 12V PSEC
to charge the batteries, as the 9V PSEC AC/DC adapter (13D0230-1) will not provide adequate
charging. It is recommended that the MSRY batteries be charged for a minimum of 8 hours.
