    September 08, 2026 4 min read

    Complete operating guide for the Serene Innovations HD-60 high definition amplified telephone.

    Full text manual (for reference)

    Operating guide for the Serene Innovations HD-60 High Definition Amplified Telephone — a wall/desk-mountable amplified telephone with adjustable handset volume and tone control, memory dialing, and a low-battery/hold indicator, designed for hard-of-hearing users.

    Package Contents & Power

    Use only a Class 2 power adapter, 9VDC, 300mA. Connect the phone as shown in the manual's wiring diagram; lift the handset to test for a dial tone.

    Feature Identification (Key Controls)

    • Handset hook — for wall-mounting use only
    • One-touch memory dialing buttons
    • Hold — puts a call on hold and mutes the handset; lifting the handset or a quick press of the hook switch releases hold
    • Prog — programs a number into memory
    • Flash — switches between the current call and call waiting
    • Memory — access to ten two-touch memories (press Memory, then a keypad number)
    • Redial — redials the last dialed number
    • Audio output jack — for connecting a neck-loop or other assistive listening device
    • Ringer Tone — selects a ring tone to suit your hearing
    • Ringer Volume — selects ringing volume
    • Tone/Pulse switch — selects tone (faster) or pulse dialing
    • Amplify — manually turns the powerful handset amplifier on/off
    • Tone dial — enhances speech clarity; positions 1–4 boost low, mid, mid-high, and high tones respectively
    • Volume — adjusts handset volume
    • Low Battery indicator — lights when backup batteries need replacing
    • Call-on-hold visual indicator
    • Amplifier Auto On/Off switch — ON: amplifier activates automatically at the last-used level every time you lift the handset; OFF: you must press Amplify manually each call
    • Battery compartment — install 4 AA batteries as backup power; without batteries the phone still works as an ordinary telephone (no amplification/tone control) during a power outage

    Amplifying Incoming Sounds

    Automatically

    1. Slide the Amplifier Auto On/Off switch (underside) to ON.
    2. While on a call, adjust the Volume switch to a comfortable level.
    3. Adjust the Tone switch until incoming voice is clear — only needed the first time; the setting is remembered for future calls.
    4. The phone automatically returns to this amplifier setting on every future call.
    5. To turn off the amplifier, press the Amplify button; press again to restore the previous setting.

    Manually

    1. While on the phone, press Amplify to turn the amplifier on (it lights up).
    2. Adjust Volume to a comfortable level.
    3. Adjust Tone until incoming voice is clear (only needed once; setting is remembered).

    Programming & Dialing One-Touch Memories

    1. Lift the handset, press PROG.
    2. Dial the phone number to save (max 15 digits).
    3. Press PROG again.
    4. Press the memory button to store the number under, then hang up.
    5. To dial, lift the handset and press the appropriate memory button.

    Automatic Off-Hook Alert

    The HD-60 alerts you when any phone on the line has been left off-hook too long — a condition that blocks new calls from coming in or going out. The HD phone detects the line's warning signal and alerts with loud rings and bright flashes. Check that all handsets are properly on their cradle.

    Wall Mounting

    1. Slide out the handset hook, turn it upside down, and reinsert — this keeps the handset in place when wall-mounted.
    2. Fit the wall mount bracket into the base of the phone.
    3. Connect the short phone cord. Align mounting holes over the wall plate screw heads (adjust screw protrusion with a screwdriver if needed) and slide the phone downward slightly to lock it in place.

    Important Safety Instructions

    • Read all instructions before use; close supervision is needed near children.
    • Do not contact moving parts or exposed metal surfaces.
    • Only use manufacturer-recommended attachments.
    • Do not use outdoors or near water (bathtubs, sinks, wet basements, pools).
    • Unplug before servicing/cleaning; don't unplug by pulling the cord.
    • Do not operate with a damaged cord/plug or after malfunction/damage — return to an authorized service facility.
    • Use only the power cord and batteries specified in the manual; do not dispose of batteries in fire.
    • Avoid using the phone during an electrical storm (risk of shock from lightning).
    • Do not use the telephone to report a gas leak in the vicinity of the leak.

    Troubleshooting

    Issue Fix
    Phone doesn't ring or rings very softly Check the ringer volume switch on the side is set to HI or MED (not LO).
    No dial tone Check all cord connections; test the wall outlet with another phone; if still no tone, contact your phone company. If another phone in the house works, contact Customer Care.
