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.
TRANSMITTER BATTERY OPTIONS
GENERAL
ALKALINE BATTERY INSTALLATION
GENERAL
1) Remove the battery cover from the bottom of the transmitter by pushing firmly on the battery cover in the direction of the arrow
and sliding it off.
Remove the battery holder and double-check that the battery holder is plugged in. If it isn't, plug the connector on the
battery holder into the matching connector in the transmitter.
• Use ONLY a 2-Cell LiPo or LiFe battery pack of desired capacity.
• The MT-S transmitter does not feature a charge jack. For the safety of both the battery pack and the transmitter itself, the
battery pack must be removed from the transmitter during the charging process.
• Use a balance charger specifically designed to charge LiPo or LiFe battery packs. Charge the battery pack in an open
area free of any obstructions.
• When changing the connector on your battery pack to match the battery connector in the transmitter,
please observe correct polarity. Connecting with reverse polarity will damage the transmitter.
• Observe all safety precautions provided with your LiPo or LiFe battery pack.
• Do not leave the battery pack unattended during the charging process.
• If the battery pack appears swollen or otherwise damaged, do not use it or charge it. It should be discarded and replaced.
• Damage to the transmitter caused by improper use, wrong battery type, incorrect voltage or reverse polarity will not be
covered under warranty!
The transmitter has a Nominal Input Voltage range of 4.8 to 7.4 volts.
DO NOT USE A 3-CELL LiPo or LiFe
battery pack
or the transmitter will be damaged! Use a 2-Cell LiPo or LiFe battery pack only!

WARNINGS IF USING A LIPO OR LIFE BATTERY PACK
GENERAL
IMPORTANT:
Y
ou must change the transmitter battery Low Voltage Alert and Low Voltage Limit alarms to match the
battery type you're using or else you may receive erroneous low voltage alarms during use, or worse run your battery
down so low as to damage it. For more information, see the BATTERY Menu section on pages 60 through 62.
Your battery pack must not exceed 9.6 volts when fully charged or the transmitter Over Voltage alarm will sound when
the transmitter is turned ON.
