How far should I keep the Infinix Hot 10 Play X688B from my body to comply with RF exposure requirements?

A minimum separation distance of 10mm must be maintained between the user's body and the handset, including the antenna. Third-party belt-clips, holsters, and similar accessories used with this device should not contain any metallic components. Body-worn accessories that do not meet these requirements may not comply with RF exposure requirements and should be avoided. (Page 7)
