1. Getting Started

For best user experience, download the HOT Watch app from the iTunes (iPhone) or Google Play

plugged in. It can create short to the USB lines. While we provide teeth to prevent short, angled metal

surfaces can still create short.

4. Hands-On Call Usage

The Hands-on Call feature is a unique feature which provides a private call experience. It is

achieved by using a directional speaker located at the bottom of the wrist. The speaker projects

the sound from the watch strap when the user’s palm is held to his/her ear. The palm redirects

the sound to the ear. Follow the below steps to get the best audio experience.

A. Wear the watch on your wrist, close to your palm. So that the speaker is closer

to palm.

B. Cusp the palm over the ear. Make sure that bottom of your palm is not

touching the ear: otherwise the sound will be blocked.

C. Adjust the volume (scale of 1-15) if required. The default volume level for

Hands-On is 5 and Hands Free is 13 for the call, default can be changed from the

HOT Watch app in the phone. Adjust the volume to the minimum required, for

audibility and for a better private call experience.

D.Volume can be further adjusted during call with + - buttons on the screen. The

watch automatically adjusts volume in noisy environments using auto gain.

5. Energy Optimization

gestures are activated during a phone call (ringing, dial-out, call in progress, etc).

close to any metal surfaces. While teeth are provided to prevent a short circuit on the

connector, the angular contact of the connector can create a short circuit in the watch .

-At Midnight 12AM, HOTWatch connections are cleaned up.

8. Audio Switching b/w Phone and Watch during Call

When making or receiving a call from the watch, the call stays on the watch. It can be

transferred to the phone by tapping on the headset button on the phone. When making a call

from the phone, the default behavior of the phone is to push the call to a Bluetooth device

(HOT Watch in this case), but the watch pushes the call back to phone (as user is not using

watch to dial-out). This is done to ensure that the call will stay on the phone when the call is

made from or received from the phone. However, some Android phones do not work well with

this call pushback. They tend to push the call back to watch. This can cause automatic call

switch to watch during a normal phone call. To overcome this problem, a special setting

“EnbleBtOff” is provided on the watch’s Settings screen to switch off the Bluetooth (only call

audio - HFP) when a call is made from the phone. The HFP is enabled again when the call is

made from the watch or when a new call comes in. Make this setting On to prevent call

switching.

9. Bluetooth Icons

The HOT Smart Watch uses a dual mode Bluetooth device with Bluetooth Classic (2.1) and

Bluetooth Low Energy (BLE, 4.0) in one device. The Classic Bluetooth is used for call audio, data

connection, phone book access and music control. BLE is used for data connection on the

supported iOS phones (available only with iPhone 4S, iOS 7 and above). The table below lists
