Product codes The digits in the Tait Orca product code provide information about the radio’s functional parameters and various hardware options, according to the scheme outlined in Figure A-1. The product code scheme is not intended to imply that any particular combination of radio features is at present available or planned for later release. For more information on the products, contact your nearest Tait dealer. Figure A-1: The Tait Orca product code scheme The Tait product code scheme Notes: The Tait product code scheme is intended to describe the meaning of the various characters used in Tait Orca Product Codes. It is not a design-a-product menu. Supply of products not yet built can be negotiated, but are subject to commercial justification by Tait Electronics Ltd, and possible regulatory compliance. 1. Information in italics refers either to obsolete or planned new items which are not available at the issue date of this document. 09/01 IPN: 449-51000-03 2. The offer of any product in any market is subject to adequate regulatory compliance. Introduction A - 5 3. Care must be taken not to enter alpha O instead of numeral 0, or alpha I instead of numeral 1. With the exception of I as a band designator, alphas I & O will not be used in this scheme. 4. This scheme does not address coding for packed ensembles of radio, battery, charger, antenna and/or other accessories. 5.

Figure A-9: Naming convention for Tait Orca handportable user’s manuals Accessories 6. ‘V’ identifies TEL badged products are for sale in Argentina, where the name 'Tait' is registered to another Company. Table A-1 shows the accessories available for Tait Orca handportables. Of these accessories, only the chargers are serviceable. 7. ‘U’ identifies accessories which are generally Tait-badged, but an unbadged version has been produced for use with radios carrying a non-Tait badge. For more information on chargers, see Part E: Battery packs and chargers. The six battery packs available for Tait Orca handportables are also described in Part E. 8. The Compliance Code underline addresses regulator concerns that the full (3-group) code appearing on the product is not the same as the 2-group code under which Compliance was obtained. It appears only on the product label and some regulatory declarations. Fitting an accessory To fit some accessories to the radio, you will need to remove the rear accessory cover. Remove the battery, then insert the end of a key underneath the bottom edge of the accessory cover. Lift to remove the cover. This also permits the same Compliances to apply regardless of badging or minor custom variations expressed in the 3rd group. However, note that the first 2 groups of the Product Code may not necessarily be the same as the Compliance Code. Operating instructions A user’s guide is available for each radio. Figure A-9 shows the naming convention for Tait Orca radio user’s guides. A - 6 Introduction When attaching or removing an accessory, ensure that the lever is in the upright position. Once the accessory is in position, rotate the lever 90 degrees counterclockwise to lock it in place.

Standard anti-static procedures should be followed; a typical setup is shown in Figure A-1. If in doubt, contact Tait Electronics Ltd or your nearest Tait dealer. Warning!!! Repairs attempted with incorrect equipment or by untrained personnel may result in permanent damage. Caution: CMOS devices This equipment contains CMOS devices, which are susceptible to damage from static charges. Care when handling these devices is essential. For correct handling procedures, refer to manufacturers’ data books covering CMOS devices, such as Philips Data Handbook Covering CMOS Devices or Motorola CMOS Data Book Section 5 (Handling Procedures). Screw head types Torx recess head screws and Pozidriv recess head screws require the correct sized driver to achieve best performance. Most of the screws in Tait Orca handportables are Torx head screws, and so a Torx T6 driver bit is supplied as part of the service kit. Some earlier radios have Pozidriv screws. Torx head 1.8*5 mm screws should be removed using the supplied Torx T6 driver. When replacing these screws, set the driver to 2 inch pounds. Pan Pozi M2*8 mm and M2*5 mm screws should be removed using a Pozi 1 driver. When replacing these screws, set the driver to 2 inch pounds.

Troubleshooting If you are experiencing difficulty operating your Tait Orca handportable check the following items: Calibrating ■ Is the battery firmly attached to the radio? For information on calibrating Tait Orca handportables, refer to: ■ Are the battery contacts clean and unobstructed? ■ the Tait Orca Calibration Application User’s Manual or the online help. ■ Is the battery sufficiently charged? The User’s Manual is on the Tait Programming Utilities (TPU) CD-ROM, which is included, together with this manual, as part of the calibration service kit. ■ Is the antenna damaged? Test facilities If all appears to be in order but your radio still fails to operate properly, consult your local Tait dealer for assistance. Standard test facilities provide a way of testing the radio’s functions independently of normal radio operation. See Part C: Diagnostics and fault finding for a description of the test facilities available for Tait Orca handportables. ■ Is the battery charger working properly? For Fault Finding Charts see Figures C-1 to C-6 starting on page C-9. For further troubleshooting on batteries and chargers, see page E-15. Basic maintenance Your Tait Orca handportable requires no regular maintenance other than ensuring that the battery has sufficient charge, the battery contacts are kept clean and unobstructed, and that no damage has occurred to the antenna or the battery pack. General care ■ Wipe the accessory connector contacts and radio display with a dry lint-free cloth to remove any dirt, oil or grease. ■ Use a cloth dampened with clean water to clean the radio’s case and display lens, but do not immerse the radio in fluids. ■ Do not allow the radio to come into contact with detergents, alcohol, aerosol sprays or petroleum-based products as they may permanently damage the case. ■ Avoid high temperatures. If the radio overheats, it will cease to function. You will hear two short high-pitched beeps. 09/01 IPN: 449-51000-03 Introduction A - 9 A - 10 Introduction 09/01 IPN: 449-51000-03
