Introduction The Apollo SL40 meets the additional standards as detailed in the Declaration of Conformity included on page 31. Note: Unauthorized changes or modifications to the SL40 may void the compliance to required regulatory agencies and authorization for continued equipment usage. UNPACKING THE EQUIPMENT Carefully unpack the equipment. Visually inspect the package contents for any evidence of shipping damage. Retain all shipping containers and packaging material in case reshipment is necessary.
Introduction OTHER REQUIRED MATERIALS The SL40 is intended for use with standard aviation accessories. The following items are required for the installation: x comm antenna with cables x a microphone x a speaker or headphone These items may be installed dedicated to the SL40 comm or by connections to an audio panel.
Installation SECTION 2 - INSTALLATION This section describes the installation of the Apollo SL40 including mounting, wiring, and connections. A post installation check-out procedure is included at the end of this section. PRE-INSTALLATION INFORMATION Always follow good avionics installation practices per FAA Advisory Circulars (AC) 43.131A, 43.13-2A, and AC 20-67B, or later FAA approved revisions of these documents.
Installation Figure 2 Mounting Frame Assembly Figure 3 Cable Routing Once the cable assemblies are complete and the connectors are attached to the mounting frame, install the mounting frame assembly in the instrument panel.
Installation head screws so the unit will slide in and out freely. Attach the front of the mounting frame to the instrument panel. Use support brackets to attach the rear of the frame to the aircraft. To install the unit in the mounting frame, make sure the cam lock is rotated so the rear part is up, then slide the unit into the frame and tighten with the 3/32 hex tool. The unit will be pulled into the frame by the cam lock and the connectors will fully engage.
Installation used. Connect the other terminal of the switch to ground. The intercom function is enabled when the input is pulled low to ground. SERIAL INTERFACE The SL40 includes an RS232 serial port, which can be used for inputting frequency and function control commands and outputting transceiver status. This is an optional connection. When making serial connections to the SL40, use a shielded three conductor cable. Make the RxD, TxD, and ground connections on the 15 pin connector.
Installation Clamp Nut Slit 1/4" (2X) Step 1. 0.125 0.031 - Slide clamp nut over coax. - Strip coax as illustrated. - Cut two 1/4" slits in jacket 180 degrees apart. 0.375 Step 2. Braid Clamp - Slide braid clamp over end of coax and under the braid. Cap Step 3. Solder Center Conductor - Insert coax with braid clamp into connector and tighten clamp nut securely. - Solder the center conductor of the coax to the contact as illustrated. - Attach the cap and secure tightly.

Installation POST INSTALLATION CHECKOUT Once the unit is installed, complete the checkout procedure to verify proper operation. Refer to the User’s Guide for operating instructions. Mounting / Wiring Check Verify that all cables are properly secured and shields are connected to the rear of the mounting frame. Check the movement of the aircraft controls to verify that there is no interference.
Installation 5. Turn the unit off to exit the Test Mode. Mic Level Adjustment Those units with audio board p/n 415-7008-01, or later, have the ability to make adjustments to microphone sensitivity by using the MIC 1 LEVEL and MIC 2 LEVEL pages in the Test Mode. 1. Press and hold the and RCL keys while switching the unit on. 2. Turn the LARGE knob to the MIC 1 LEVEL and MIC 2 LEVEL pages. 3. Press the key to start selection (the number will flash). 4. Turn the SMALL knob to change the value.
Installation Flight Test Check A flight test is recommended as a final installation verification. The performance may be verified by contacting a ground station at a range of at least 50 nm while maintaining an appropriate altitude and over all normal flight attitudes. Performance should be checked using low, high, and mid band frequencies.
