RETEVIS RT55 VHF Marine Two Way Radio

CAUTION

• The power supply of this transceiver is DC 7.4V, please use Li-ion battery as configured.
• This transceiver should be charged by configured adaptor.
•  Do not expose it to direct sunlight for a long time, do not place it in environment or near any heating devices with tempera­tures below -20°C or above +55°C.
•  If it emits smoke or strange odours, remove the battery from the product immediately and contact us or the local dealer.
•  Cannot be transmitted without antenna installed, or the devices will be damaged.
• Do not operate it and power off in flammable, explosive environment.
• KEEP the transceiver at least 1 meter away from your vessel’s magnetic navigation compass.
• BE CAREFUL, the transceiver meets IP-67 requirements for waterproof protection. However, once the transceiver has been dropped, waterproof protection cannot be guaranteed because of possible damage to the transceiver’s case or the waterproof seal.
• MAKE SURE transceiver antenna, earphone jack cover and battery cover are dry before attachment. Exposing the inside of the transceiver to water will result in serious damage to the transceiver.
•  Do not put the battery separately in the water or contact with wet material. Do not short circuit the battery.

Recommendation
Clean the transceiver thoroughly with fresh water after exposure to saltwater, and dry it before operating. Otherwise, the transceiver’s keys and control components may become unusable due to salt crystallization.
NOTE:
DO NOT submerge the transceiver in water if there is any reason to suspect the waterproof protection may not be effective. for example, in cases where the battery cover or DC Jack cap rubber seal is damaged, the transceiver/battery cover/DC Jack cap is cracked or broken ,or the transceiver has been dropped, or when the battery cover, antenna or DC Jack cap are detached from the transceiver.

 FEATURES

SCAN OPERATION

Scan Types
Scanning is an efficient way to locate signals quickly over a wide frequency range. The transceiver has priority scan and normal scan.

• Weather channels will be scanned also when weather alert function activated.

• Set TAG channels before scan. Cancel tag for channels not need
  to be scanned.

• Normal Scan
  It searches through all TAG channels in sequence. However, unlike priority scan, Channel 16 is not checked unless channel 16 is set as a TAG channel.

• Priority Scan
  A priority scan sequentially searches through all TAG channels while monitoring Channel 16 when a signal is detected on Channel 16, the scan pauses until the signal disappears; when a signal is detected on a channel other than Channel 16, the scan switches to Dual-watch, until the signal disappears.
  

• Normal Scan
  

• Priority Scan

Set TAG Channels
For more efficient scanning, set the desired channels as TAG channels or clear the TAG setting from unwanted channels. Channels that are not tagged will be skipped during scanning.
Set /cancel single TAG channel

1. Push [CH] to select desired channel group.
2.  Push [Tl or [Tl to select the desired channel to be set as a TAG Channel.
3.  Push and hold [FAV/TAG] for 1.5 seconds, to set the displayed channel as a TAG Channel.
   • “TAG” appears in the function display.
4.  To cancel the TAG channel setting, push and hold [FAV/TAG] for 1.5seconds.

• ‘”TAG “disappears.
•  Set/cancel all TAG channels

1. While pushing and holding [FAV/TAG], press[ ~ ]ON to clear all TAG channels in the selected channel group.
2.  Repeat above procedure to set all channels as TAG channels.

• Scan Operation

Set scan resume timer in the set mode.

1. Push [SCAN] to start normal scan or priority scan.
   •  “SCAN” Blinks. D
   •  “16” appears on the sub channel readout during a priority scan.
