GENERAL
The MT-4S transmitter's Operating Voltage Range is 4.0 to 9.6 volts. This allows you to use several different battery options (not
included), depending on your preference.
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.
Ni-Cd/Ni-MH - Rechargeable Ni-Cd or Ni-MH batteries of desired capacity can be used in place of the Alkaline batteries.
Using rechargeable Ni-Cd or Ni-MH batteries is more convenient and cheaper in the long run. The Higher capacity batteries
will also provide longer usage time than most Alkaline batteries.
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.
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.
3) Slide the battery cover back onto the transmitter and push it firmly until it 'clicks' closed.
When installing the batteries, 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.
1) Remove the battery cover from the bottom of the transmitter by pushing firmly on the battery cover in the direction of the arrow.
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).
The MT-4S transmitter features a Charging Jack that can be used with the Airtronics 95034 Dual Output charger (available
separately) to charge the optional Ni-Cd or Ni-MH batteries. This allows you to charge these batteries without removing them
from the transmitter. A Charging Jack is located on the Left side of the transmitter. For more information, see the
Transmitter
Overview Diagrams
section on page XX.
WARNING: Do NOT attempt to recharge Alkaline batteries. Only Ni-Cd or Ni-MH batteries should be charged through the
transmitter's Charging Jack, using only the Airtronics 95034 Dual Output charger or equivalent overnight/slow charger. Do
NOT attempt to charge a LiPo or LiFe battery pack through the Charging Jack.
Do NOT use the Charging Jack with a fast charger or a peak-detection charger, or the transmitter could be damaged!
If you use a fast charger or a peak-detection charger to charge the transmitter batteries, the battery holder must be removed
from the transmitter first. The circuitry within the transmitter will interfere with the peak-detection charger's normal operation,
resulting in over-charging and damaging the batteries and possibly the transmitter itself. In addition, the higher charge
rate common in many fast chargers can damage the transmitter's circuitry.
Damage caused by fast-charging through the transmitter or using an incorrect battery type will not be covered under
warranty!
• Use ONLY a 2 Cell LiPo or LiFe battery pack of desired capacity.
• Do NOT charge your LiPo or LiFe battery pack through the Charging Jack. The battery pack MUST be removed from the
transmitter prior to charging or the transmitter could be damaged. For more information, see the WARNING in the
Transmitter
Battery Charging Options
section above.
• Use a balance charger specifically designed to charge LiPo or LiFe battery packs.
• 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.
• Damage to the transmitter caused by improper use, wrong battery type, incorrect voltage, reverse polarity or charging
through the Charging Jack 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!
