Servicing Tait Orca handportables

The Tait Orca series of handportables is a range

of high performance, microprocessor-control-

led radios manufactured using an RF-shielded

PCB and high-density SMD componentry.

The manufacturing process does not allow

direct servicing access to components on the

main PCB, although replacement PCBs are

available on an exchange basis. Service repairs

of Tait Orca handportables are therefore limit-

ed to key mechanical and ancillary devices

associated with the main PCB. These include:

■the front panel assembly;

■the lens (Orca Excel and Orca Eclipse);

■the PTT keypad;

■the speaker;

■the keypad (Orca Excel and Orca Eclipse);

■the volume plate and keypad (Orca

Eclipse);

■the LCD display (Orca Excel and Orca

Eclipse);

■the shield, complete with user interface

PCB assembly and polyester dome (Orca

Excel and Orca Eclipse);

■the main PCB assembly;

■the antenna connector;

■the channel selector switch (Orca Elan and

Orca Excel);

■the volume control switch (Orca Elan and

Orca Excel);

■the microphone;

■the speaker contacts;

■the battery contacts;

■the PTT tact switch;

■the RF out assembly; and

■the auxiliary flexible PCB.

The repair of PCB-related faults is the respon-

sibility of the Tait repair centre, Tait Commu-

nications Ltd, Christchurch, New Zealand.

Detailed schematics and component location

information for the main PCB may be obtained

from the Customer Service Department at Tait

Electronics Ltd. Contact your Tait dealer for

more information about these two services.

The Tait Orca series of handportables

There are three Tait Orca series handportables

available:

■the Orca Elan;

■the Orca Excel; and

■the Orca Eclipse.

This manual includes information specific to

all three handportables. As new features and

manual will be released.

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 combi-

nation of radio features is at present available

or planned for later release. For more informa-

tion on the products, contact your nearest Tait

dealer.

Figure A-1: The Tait Orca product code scheme

The Tait product code scheme

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.

Notes:

1. Information in italics refers either to

obsolete or planned new items which are

not available at the issue date of this

document.

2. The offer of any product in any market is

subject to adequate regulatory compliance.

A - 6 Introduction 09/01 IPN: 449-51000-03

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, charg-

er, antenna and/or other accessories.

5. Lower-case alpha character-location desig-

nation can be used as a convenient short-

hand when listing products or compliances

such as TOP-B2xy0, where x = 1~3, y = 1 or

2.

6. ‘V’ identifies TEL badged products are for

sale in Argentina, where the name 'Tait' is

registered to another Company.

7. ‘U’ identifies accessories which are general-

ly Tait-badged, but an unbadged version

has been produced for use with radios

carrying a non-Tait badge.

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.

This also permits the same Compliances to

apply regardless of badging or minor custom

variations expressed in the 3rd group. Howev-

er, 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.

Important information

Basic servicing precautions

Tait Orca handportables require specialised

servicing techniques and should only be

serviced at an approved Tait service centre

equipped with the necessary facilities.

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.

Programming

ming Utilities (TPU) CD-ROM, which is

included, together with this manual, as part of

the calibration service kit.

Calibrating

For information on calibrating Tait Orca

handportables, refer to:

■the Tait Orca Calibration Application User’s

Manual or the online help.

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.

Test facilities

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 facili-

ties available for Tait Orca handportables.

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.

Troubleshooting

If you are experiencing difficulty operating

your Tait Orca handportable check the follow-

ing items:

■Is the battery firmly attached to the radio?

■Are the battery contacts clean and

unobstructed?

■Is the battery sufficiently charged?

■Is the battery charger working properly?

■Is the antenna damaged?

For Fault Finding Charts see Figures C-1 to C-6

starting on page C-9. For further troubleshoot-

ing on batteries and chargers, see page E-15.

If all appears to be in order but your radio still

fails to operate properly, consult your local

Tait dealer for assistance.
