Certain chemicals and vapor can harm plastic and metal plating. Do not use solvents or sprays to
clean your radio.
NOTE: Regardless of the use-case scenario, this cleaning procedure does not guarantee the
lifespan of the radio.
Vent Port Handling Precaution
The portable device has a vent port that allows for pressure equalization in the device. The pressure
equalization vent is located at the battery compartment area. Never touch the equalization vent.
Ensure that no oily substances come in contact with this vent. Never poke this vent with any objects,
such as needles, tweezers, or screwdrivers. This create a leak path into the device and lost the
submersibility of the device.
Care After Submersion
The radio (device with antenna and battery assembled) is IP67 compliant. It is fully protected from
dust, and can withstand being submerged up to 30 minutes in one meter of static water.
If the device has been submerged in water, shake the device to remove any water that is trapped
inside the speaker grille and microphone port. Otherwise, the water will decrease the audio quality and
connectivity performance of the device.
Ensure that no water has penetrated the seal. Check the interface if any accessory or the Universal
Connector Dust Cover is covering the Universal Connector and Bottom Connector. Water left in this
interface can degrade the performance of the accessories.
5.2
Safe Handling of CMOS and LDMOS Devices
Complementary Metal Oxide Semiconductor (CMOS) and Laterally Diffused Metal Oxide
Semiconductor (LDMOS) devices are used in this family of radios, and are susceptible to damage
by electrostatic or high-voltage charges.
Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special
precautions must be taken to prevent device damage during disassembly, troubleshooting, and repair.
