WateRpRoof coMponent
Your new Spektrum™ receiver has been designed and built to allow you
to operate your vehicle in many wet conditions, including puddles, creeks,
wet grass, snow and even rain.
While waterproof, this component has not been designed to be immersed in
water for long periods of time and should NOT be treated like a submarine.
In addition, most metal parts, including any screws and nuts, as well as the
contacts in the electrical cables, will be susceptible to corrosion if additional
maintenance is not performed after running in wet conditions.
To maximize the long-term performance of your receiver and to keep the
warranty intact, it should only be used as described in the "Usage Conditions"
section of this manual. Additionally, the procedures described in the "Wet
Conditions Maintenance" section must be performed regularly if you choose
to run in wet conditions. If you are not willing to perform the additional care
and maintenance required, then you should not operate your vehicle in those
conditions.
cautIon: Failure to exercise caution while using this product and
comply with the following precautions could result in product malfunction
and/or void the warranty.

general precautions

Read through the wet conditions maintenance procedures and make sure
that you have all the tools you will need to properly maintain your receiver.
Do not operate your receiver where it could come in contact with salt water
(ocean water or water on salt-covered roads), contaminated or polluted
water. Salt water is very conductive and highly corrosive, so use caution.

usage conditions

Your receiver will operate successfully in any of the following, individual-usage
scenarios:
2 hours continuous operation in dew-covered (damp) grass or vegetation.
2 hours continuous operation in heavy fog (95% humidity, saturated air,
condensing water).
1 hour continuous operation in light rain (< 0.10 in / 2.5mm per hour).
15 minutes continuous operation in heavy rain (> 0.30 in / 7.6mm per hour).
1 hour continuous operation in light sleet (< 0.10 in / 2.5mm per hour).
1 hour continuous operation in light snow (< 0.25 in / 6.35mm per hour).
45 minutes continuous operation in standing or running fresh water (the
water level should always remain below the vehicle frame), or constant
splashing water, without any immersion of waterproof component(s).
