General Safety Information for Service Personnel
CAUTION
Risk of wrong installation
Wrong positioning of the bearing stand will obstruct to take bearings.
Always make sure that the bearing stand is so positioned that the ves-
sel’s superstructure does not unduly obstruct the view of the horizon.
In case one bearing stand does not allow to take bearings in a full circle
of 360°, a second bearing stand must be installed for compensation.
CAUTION
Risk of damage
The compass repeaters are heavy instruments. The compass repeater
cables are not designed for holding the repeater just with the cable.
Never hold or transport the repeater on the cable alone when installing
or wearing a compass repeater.
CAUTION
Risk of damage
The bearing repeater is a heavy instrument.
To avoid any damage during installation of the bearing repeater into the
gimbal ring, the installation should be carried out by two service persons.
CAUTION
Risk of malfunction
Do not lengthen the cable between the bulkhead repeater and the con-
nection box as the USB service port will not work reliably.
If the connection box cannot be installed at an accessible location close
to the repeater, it will be required to unmount and disassemble the
repeater to gain access to the internal USB receptacle when configuring
or servicing the device.
If the repeater cable is connected directly to shipside terminals, the exter-
nal USB port may not be used and its four wires must be connected to
blind terminals.
CAUTION
Risk of damage through unauthorized service
The housing of the bearing repeater 5016-CA is designed for increased
watertightness and shall therefore not be opened in the field.
Opening the housing in the field will diminish the watertightness and
may lead to condensation forming on the inside surfaces, especially the
top glass, at a later point in time.
Never open the bearing repeater housing in the field.
Always return a defective bearing repeater to Sperry Marine.
CAUTION
Risk of damage through unauthorized service
The analogue compass repeaters are complex electronic devices, which
are not serviceable in the field down to the level of individual circuit com-
ponents.
Defective units must be sent back to Sperry Marine for repair.
CAUTION
Risk of damage of electrostatic-discharge-sensitive components
The analogue compass repeaters contain electrostatic sensitive compo-
nents. Electrostatic discharge may permanently damage components.
When servicing an analogue compass repeater, take precautions to pre-
vent electrostatic discharge. Avoid touching any of the electronic cir-
cuitry.
