PRESIDENT WASHINGTON HAM Radio

Introduction

Welcome to the world of the new generation of radios. The new PRESIDENT range gives you access to top performance transceiver equipment. With the use of up-to-date technology, which guarantees unprecedented quality, your PRESIDENT WASHINGTON is a new step in personal communication and is the surest choice for the most demanding of professional radio users. To ensure that you make the most of all its capacities, we advise you to read carefully this manual before installing and using your PRESIDENT WASHINGTON.

Your PRESIDENT WASHINGTON is equipped with the APM (Automatic Power Management) system, an advanced thermal management system designed to maintain optimal performance even in variable temperature conditions. The system continuously monitors the internal temperature of your radio station. In case of temperature increase, if you have connected fans (optional), they can automatically start to cool the radio station. If necessary, the power of your station is automatically adjusted to reduce generated heat. Additionally, you can customize thermal protection settings by setting your own temperature threshold for fan activation, if desired. This combination of options ensures efficient thermal management, guaranteeing the durability and reliability of your radio station in all usage conditions.

Safety and Warnings

Parts marked with [USA symbol] only concern USA and parts marked with [EU symbol] only concern EU.

[Warning symbol] WARNING: This product can expose you to chemicals including Lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.

[Warning symbol] WARNING!

• The use of this equipment involves the possession of a Radio Amateur license.
• Before using, be careful never to transmit without first having connected the antenna (connection "B" situated on the back panel of the equipment) or without having set the SWR (Standing Wave Ratio) ! Failure to do so may result in destruction of the power amplifier, which is not covered by the warranty.

The warranty of this transceiver is valid only in the country of purchase.

Installation

1) Where and How to Mount Your Mobile Radio

• Choose a well-ventilated place most appropriate setting from a simple and practical point of view.
• Your radio should not interfere with the driver or passengers.
• Provide for the passing and protection of different wires (e.g., power, antenna, accessory cabling) so that they do not in any way interfere with the driving of the vehicle.
• To install your equipment, use the cradle (1) and the self-tapping screws (2) provided (drilling diameter 3.2 mm). Take care not to damage the vehicle's electrical system while drilling the dash board.
• Insert the rubber joints (3) between the radio and its support as these have a shock-absorbing effect which permits gentle orientation and tightening of the set.
• Choose where to place the microphone support and remember that the microphone cord must stretch to the driver without interfering with the controls of the vehicle.

2) Antenna Installation

a) Choosing Your Antenna

• For radios, the longer the antenna, the better its results. Your dealer will be able to help you with your choice of antenna.

b) Mobile Antenna

• Must be fixed to the vehicle where there is a maximum of metallic surface (ground plane), away from windscreen mountings.
• If you already have a radio-telephone antenna installed, the transceiver antenna should be higher than this.
• There are two types of antenna: pre-regulated which should be used on a good ground plane (e.g. car roof or lid of the boot), and adjustable which offer a much larger range and can be used on a smaller ground plane (see "HOW TO ADJUST SWR", below).
• For an antenna which must be fixed by drilling, ensure good contact between the antenna and the ground plane. Lightly scratch the surface where the screw and tightening star are to be placed.

• Be careful not to pinch or flatten the coaxial cable (as this runs the risk of break down and/or short-circuiting).
• Connect the antenna (B).

c) Fixed Antenna

• A fixed antenna should be installed in as clear space as possible.
• If fixed to a mast, it may be necessary to stay it according to local laws.

3) Power Connection

• Your PRESIDENT WASHINGTON is protected against inversion of polarities. Check all connections before switching on.
• Equipment must be supplied with a continued current of 12 volts (A).
• Most cars and lorries are negative earth. Check this by ensuring the negative terminal of the battery is connected to the engine block or chassis. Consult your dealer if not.
• WARNING: Lorries generally have two batteries (24 volts). A 24/12 volt converter (type CV 24/12 PRESIDENT) may be necessary.
• Carry out connection steps with the power cable disconnected.
• Check that the battery is 12 volts.
• Locate positive (+) and negative (-) battery terminals (red/black). Use same or superior cable type if lengthening the power cable.
• Connect the power cable directly to the battery (connecting to car-radio wiring may increase interference).
• Connect the red wire (+) to the positive terminal and the black wire (-) to the negative terminal of the battery.
• Connect the power cable to your transceiver.
• WARNING: Never replace the original fuse with one of a different value.

4) Basic Operations Before First Use

• Connect the microphone.
• Check antenna connections.
• Turn on the radio by turning the VOL knob (1) clockwise.
• Turn the squelch SQ knob (2) to minimum (M).
• Adjust volume to a comfortable level.
• Go to channel 20 using the CH rotary knob (4) or UP/DN keys (19) on the microphone.

5) How to Adjust SWR (Standing Wave Ratio)

Warning: Perform this adjustment for the first time use and whenever the antenna is repositioned. Carry out in an obstacle-free area.

a) Adjustment with internal SWR-meter

See function SWR CALIBRATION page 15.

b) Adjustment with external SWR-meter (e.g. TOS-1 PRESIDENT)

• To connect the SWR meter: Connect between transceiver and antenna, as close as possible to the radio (use max 40 cm cable, type President CA 2C).
• To adjust the SWR meter:
  • In AM or FM, use CH knob (4) or UP/DN keys (19) to position the device in the middle of the band. Verify values on external frequencies if possible.
  • Put the SWR-meter switch to FWD (calibration).
  • Press the PTT switch (18) to transmit.
  • Bring the index needle to [calibration symbol] using the calibration key.
  • Change switch to REF (SWR reading). Reading should be as near as possible to 1. If not, readjust antenna. (SWR reading between 1 and 1.8 is acceptable).
  • Recalibrate SWR meter after each antenna adjustment.

WARNING: Use cables less than 3m for connections to avoid losses and attenuations.

Your transceiver is now ready for use.
