3.3.3 Cable features
In the United States and Canada, the cable used should be a UL Listed, SAE type GPT Cable, min 18AWG.
Note
The cable approvals may depend on the requirements set in the country where the equipment is going
to be installed. The cable must always be 18 A WG or greater.
3.3.4 Replacing the lithium battery
The router has an internal lithium battery to maintain the internal clock.
To replace said battery, you need to open the device's upper casing. To do this, you need to remove the screws loc-
ated in the upper part of the front and rear panels.
Warning
There is a risk of the battery exploding if it is replaced with one that is not recommended or one of a dif-
ferent type. Please dispose of the used batteries in accordance with the environmental recycling in-
structions given in this document.
3.3.5 Configuring Power Management
The OA5725A is endowed with a power management system that allows the following:
- the device will only switch on when the vehicle has been switched on.
- when installed, the device switches off a short time after the vehicle has been switched off, i.e. there is a slight
delay with respect to the vehicle being switched off. The purpose of this is that the device, when installed, does not
disconnect during short stops.
This feature is configured through the internal microswitches ( SW100): the duration of the delay however is con-
figured through the configuration command.
The microswitches are located in the device, as shown in
