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.

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 .

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
the Bluetooth profiles supported by the watch.
