MT- S
2.4GHZ FH4T RADIO SYSTEM USER'S GUIDE
Telemetry System with Sanwa Synchronized Link Support
The MT-S transmitter has a Nominal Input Voltage range of 4.8 to 7.4 volts and an Operating Voltage Range of 4.0 to 9.6 volts.
This allows you to use several different battery types, depending on your preference. Use the information below to determine
what type of battery to use.
Alkaline - In the default configuration, the transmitter is designed to be powered using four 'AA' Alkaline batteries. This results
in a transmitter that is lightweight and well-balanced for unmatched comfort. Install the four 'AA' Alkaline batteries into the
battery holder included.
NiMH - Rechargeable NiMH batteries of desired capacity can be used in place of the Alkaline batteries. Using rechargeable
NiMH batteries is more convenient and cheaper in the long run. The higher capacity batteries will also provide longer usage
time than most Alkaline batteries. Install the four NiMH batteries into the battery holder included.
LiPo or LiFe - A 2-cell LiPo or LiFe battery pack can be used to power the transmitter. These battery packs are popular due
to their light weight and high capacity for long usage time between charges. Remove the battery holder first, then install the
LiPo or LiFe battery pack.
Transmitter power output, range and speed are the same, regardless of the battery type used. If using a LiPo or LiFe
battery pack, please read the Warnings if Using a LiPo or LiFe Battery Pack section below.
2) Install four fresh 'AA' Alkaline batteries into the battery holder, making sure that the polarity is correct. The direction that each
battery should be installed is molded into the bottom of the battery holder (+ Positive and - Negative).
3) Reinstall the battery holder into the transmitter, making sure that the batteries toward bottom of the transmitter (so the
smooth bottom of the battery holder will be toward the battery cover). This will prevent the battery cover from hitting or
catching on the batteries when you reinstall it.
4) Slide the battery cover back onto the transmitter and push it firmly until it 'clicks' closed.
