This unit is a navigational system consisting of a radio-positioning receiver making use of signals from the NAVSTAR GPS (Global Positioning System). The system offers simultaneously, high accuracy, continuous cover and worldwide availability. This unit may be operated as a purely standalone system supplied by its own internal batteries or may be connected to an external 12v supply and integrated with further instumentation via a NMEA data link. For fixed installation a bracket is provided to allow secure fixing in a wide variaty of positions. 8 Apelco GPS11 Installation and Operation Handbook Important Information All Raytheon equipment and accessories are designed to the highest standard for use in the leisure marine environment. Their design and manufacture conforms to the latest Electromagnetic Compatibility (EMC) standards, but good installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product. To avoid the risk of EMC problems, all Raytheon equipment and cables connected to it should be; t At least 1m (3 feet) from any equipment transmitting or cables carrying radio signals e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance should be increased to 2m (7ft). At least 20m (66 feet) from large vessels equipped with radar. More than 2m (7 feet) from the direct path of a radar beam. t t The following points should also be noted; t Genuine Raytheon cables should be used at all times. Cutting and rejoining these cables can compromise EMC performance and so should be avoided unless doing so is detailed in the installation manual. Raytheon equipment should be serviced only by authorised Raytheon service engineers. They will ensure that service procedures and replacement parts used will not affect EMC performance. There are no user serviceable parts in any Raytheon product. Voltage drops below 10v in the power supply to our products can cause the equipment to reset. This will not damage the equipment but will cause the loss of some information and can change the operating mode. This most frequently happens during engine starting, and so to reduce the risk of this occurring, it is recommended that the equipment is supplied from a different battery than the one used for engine start. Some products generate high voltages, and so never handle the cables/ connectors when power is being supplied to the equipment. Always check the installation before going to sea to make sure that it is not affected by radio transmissions, engine starting etc. In some installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but can lead to it resetting, or momentarily result in faulty operation. t t t t t Please keep these notes for future reference. Chapter 2: Installation 9 Chapter 2: Installation This chapter covers installation of the support bracket and external cable of the GPS11. If the unit is to be used purely as a standalone handheld GPS then this chapter may be ignored. 2.1 "Velcro" Strap mounting The unit is supplied with a "Velcro" strip which may be attached to the rear case using the lanyard slots. Ensure that the strap is pulled tight and the end tabs turned back and secured to the main strap. Attach the fixing strip to the desired surface using glue or double sided tape or sew the strip onto clothing. 2.2 Bracket Mounting ( GPS11 plus only) The unit is supplied with a universal mounting bracket (selected models only) which will allow your GPS to be slotted into a permanent storage/operating position. 2.2.1 Fixed to a vertical bulkhead Select your desired position and screw the backplate (1) to the vertical bulkhead. Slot the main bracket (2) onto the top tab of the backplate and then push the bottom of the main bracket back, to allow the supplied finger bolt (3) to secure the base of the bracket. D4117-1 10 Apelco GPS11 Installation and Operation Handbook 2.2.2 Fixed to a horizontal surface The bracket may be fixed such that it may be adjusted vertically only or such that it may be rotated and adjusted vertically. For vertical adjustment only screw the backplate (1) to the desired horizontal surface and then secure the main bracket (2) at the desired angle using the finger bolt (3). D4116-1 Chapter 2: Installation 11 To allow the bracket to be rotated assemble the backplate (1) to the main bracket (2) using the finger bolt (3). The angle may be adjusted later if required. Select your desired position and screw the base plate (4) to the horizontal surface, then attach the backplate to the baseplate using the finger bolt (5). D4118-1 12 Apelco GPS11 Installation and Operation Handbook 2.2.3 Fixed to a rail The bracket may be mounted to a rail using the same method as for mounting to a horizontal surface but by reversing the base plate and using stainless steel nuts and bolts (not supplied) to clamp the base plate to the back plate around the rail. D4119-1 2.3 Accessories Carry Case Part No. P36003 A soft carry case is available to protect your GPS11 unit. Bracket Assembly Part No. P36004 (included in GPS11 plus) To allow the standard GPS11 unit to be bracket mounted the bracket assembly that is included in the GPS11 plus kit is available separately.
