You should hear the radio snap into place and the release button will pop up. Locking a Radio in the Vehicle Kit You can use the supplied key to lock the radio into the vehicle kit when you leave the vehicle unattended. To lock the radio in the vehicle kit, insert the supplied key in the lock and turn it clockwise. 09/01 IPN: M5000-00-102 Tait Orca Vehicle Kit F - 11 To unlock the radio from the vehicle kit, turn the key counterclockwise. 8 1 charger status LED Removing the Radio To remove the radio from the vehicle kit, push the release button down. The radio can now be removed from the radio cavity. 2 radio cavity 7 3 charger pins 6 4 locating pegs Charging the Battery Once the radio is inserted into the radio cavity, the charger status LED will glow amber for three seconds, then red. When the LED glows green, the battery is charged to a minimum of 70% capacity. If the battery is too hot or too cold, the LED will glow amber until the battery temperature is within the safe range for recharging (0ºC to 50ºC). If the indicator remains amber, consider turning on your air conditioning. Optimum battery charging performance is obtained between 15ºC and 25ºC. 5 locking 4 mechanism 4 6 radio interface 7 lock 8 release button 3 Charge times when the radio is turned off are: ■ up to 1½ hours for the 1100 mAh NiCd battery; and ■ up to 2 hours for the 1500 mAh NiCd. battery. You can still use the radio while the battery is being charged, but the charge times will vary, depending on how much the radio is being used. The vehicle charger functional indicators are summarised in Table F-4.

Volume can be adjusted from the radio’s volume control. The standard installation results in the charger and external speaker being turned off when the ignition is off. If the vehicle kit determines that the vehicle’s battery is too low (less than 11 V), the vehicle kit will turn off. 09/01 IPN: M5000-00-102 WARNING: The vehicle kit uses less than 30 mA from the vehicle’s battery when the ignition is off. For this reason, if you are leaving your vehicle unattended for an extended period of time (for example, more than one month), the positive fuse should be removed. Vehicle Kit Specifications Basic Care and Safety Supply voltage ■ It is essential to short condition your battery weekly using the desktop fast charger. ■ Wipe the radio contacts and accessory interface with a dry, lint-free cloth to remove any dirt, oil or grease. ■ Do not allow the vehicle kit to come into contact with detergents, alcohols, aerosol sprays or petroleum-based products, as they may permanently damage the case.

Servicing Warnings: Screw Head Types There are four different types of Torx screws used in the vehicle kit: KC22x6, KC25x6, KC30x8 and KC30x10. All these screws require a Torx head screwdriver. When tightening any screws, be careful not to strip the threads in the plastic mouldings by exerting too much force. The following table explains the torque settings required for the different Torx screw types. Figure F-8: Vehicle kit torque specifications Quantity Torque (in.lb) 346-10022-06 2 2 KC25x6 346-10025-06 3 2 KC30x8 346-10030-08 2 6 KC30x10 346-10030-10 4 6 Screw Type IPN KC22x6 Removing the Vehicle Kit Back Cover The back cover is held to the front moulding by two plastic clips at the base of the unit. Insert the tip of a round screwdriver into the two holes at the bottom of the rear panel. Lever the tip upwards towards the top of the unit. downwards while undoing these screws, as there are springs underneath. Unplug the loom from the accessory probe PCB. Carefully use narrow nose pliers to unplug the MCX connector from the accessory probe PCB. Now remove the two KC22x6 screws on the front of the vehicle kit holding the accessory probe PCB into the front moulding. The accessory probe PCB can now be tilted upwards and removed from the moulding. Fit the seal onto the new accessory probe PCB and reassemble the vehicle kit. Read the assembly instructions for more information. Replacing the Charger Probe PCB Remove the back cover and unplug the accessory loom at the top of the options PCB. Lift the options/charger PCB assembly out of the front moulding, until the charger loom is accessible. Unplug the charger loom and remove both PCBs from the front moulding. Note that these PCBs are still attached via the RF cable. Unscrew the two KC30x8 screws holding the charger probe moulding into the front moulding, and slide out the probe moulding. Unscrew the three KC25x6 screws holding the probe PCB to the probe moulding. Fit the seal onto the new charger probe PCB and reassemble the vehicle kit. Hold the unit in such a way that your forefinger and thumb exert a slight pressure to separate the rear panel away from the front moulding, while you lever the clips with the screwdriver. Removing the Options or Charger PCBs Remove the two DB25 fasteners holding the back panel to the accessory/options connector. Remove the two KC30x10 screws holding the back plate to the audio PA. Unclip the backplate from the options PCB. The PCBs can now be unplugged and replaced. Replacing the Accessory Probe PCB Remove the back cover and unplug the accessory loom at the top of the options PCB. Unscrew the two KC30x10 screws holding the trigger assembly together. The trigger assembly can now be lifted out. When putting the options/charger assembly back into the front moulding, make sure that the charger PCB is running in its tracks. Be careful that you do not bump the LED at the bottom of the charger PCB; the PCB does not require any force to insert. Note that the trigger assembly must be pressed F - 14 Tait Orca Vehicle Kit 09/01 IPN: M5000-00-102 Reassembling the Vehicle Kit To assemble the vehicle kit, reverse the disassembly process. Note that when doing up the KC30x10 screws the threads in the plastic PA moulding must not be stripped. It is important that the audio PA is held firmly against the backplate, as the backplate serves as a heatsink. Trigger Reassembly When reassembling the trigger assembly, insert the peg moulding into the front panel. Insert the quarter turn moulding and rotate it until the peg moulding prevents it from turning. Drop the two springs into the peg moulding. While pressing in the trigger cap, replace the trigger assembly. While holding the trigger assembly cover together (before doing up the screws) check that the locking mechanism works correctly. To do this, press in the locating pegs and check that the trigger cap pops up. Press the trigger cap down and check that the locating pegs pop out. If the trigger assembly does not work correctly, check that the quarter turn moulding is in the correct position and repeat the assembly process. Spares Kits The following table shows a list of spares kits which are currently available for servicing Tait Orca vehicle kits. These can be ordered from you local Tait dealer. Table F-6: Vehicle kit spares kits Product code Description TOPA-SP-301 Vehicle kit spares kit TOPA-SP-302 Vehicle kit reskinning kit The contents of these kits are shown in Tables F-6 and F-7. Note that the ‘IPN’ column is the ten digit ‘internal part number’ which uniquely identifies any component used in a Tait product. The numbers in the ‘Legend’ column refer to Figure numbers in which the spares item is shown. The numbers in brackets refer to the numbered legend within the figure, where appropriate. Tighten the two KC30x10 trigger assembly screws, while holding the trigger assembly in place. Rear Cover Reassembly Locate the top of the rear cover into the back of the trigger assembly. Press the bottom of the rear cover to click/lock the cover into the front moulding. 09/01 IPN: M5000-00-102 Tait Orca Vehicle Kit F - 15
